Brief Description: ================== PC-CONFIG is principally a program which can list the componenets of your computer without you having to touch a single screw to look inside While there are several of this kind of program (let's call them computer test or diagnostic programs) available on the international commercial market, you will certainly want to put PC-CONFIG on the short list. The main users of PC-CONFIG are professionionals and interested amateurs, who like to be informed over the hardware configuration of their computers, be it because they wish to make sure a computer really has what it claims to have before buying it, or because they change the hardware of their computers often and wish to confirm that everything runs properly together. The Window HARDWARE: ==================== Machine: At this point the computer BIOS is searched for possible clues as to the computer manufacturer (e.g. Commodore, Unitron....) and the computer is gererally classified (XT,AT,AT386). At the same time, particular chip-sets are tested for:- Chips & Technologies, G2-, OPTI, SIS, UMC, FOREX, ETEQ, ELITE, CONTAC, SHASTA (see also below: problems) BIOS: The copyright string found in the BIOS is displayed here. It may be that the BIOS copyright does not belong to the computer manufacturer. This is because many manufacturers use licensed versions of a BIOS. In this way, a Unitron computer for example has a Phoenix BIOS. BIOS-Date: This shows how old the BIOS-version is, und thus the age of the computer. Also checked is whether the BIOS (in computers built since 1987) is copied into shadow RAM. If BIOS calls run as quickly as normal RAM calls, it can be assumed that the BIOS has been copied into RAM. In the case of a 386 or better, shadow RAM is assumed if the call is 32 bits wide. BIOS-Extension: The address of any BIOS extension such as VGA-ROM or SCSI controller ROM is displayed Bus System: Displays whether the computer has a standard ISA (= Industry Standard Architecture) bus, an EISA (=extended ISA) bus, IBM's Microchannel Architecture (MCA), the popular VESA-Local-Bus, or Intels PCI Bus. Processor: The CPU is identified (88,86,188,186,286,386DX/SX,486DX/SX,Pentium, Cyrix486, RapidCAD,V20,V30). 80386 or 80486 processors are tested whether they are running in REAL or VIRTUAL mode (many memory managers such as 386MAX run the processor in virtual mode). The processor clock speed is displayed, together with the number of wait states on a memory access (8 and 16 bit CPUs only). Among others, these CPUs are being detected: AMD: 80486DX/4 an 486DX with tripple internal speed and 8k cache 5x86 P75: a chip with 486 pinout, external clock 33 MHz, internal 133 MHz clockspeed, 16k cache K5: chip with Pentium layout, /w 16k data and 8k code cache onboard. K6: chip with Pentium layout, /w 32k data and 32k code cache onboard. Needs 2.8V Intel: 80386SL: an 386SX version with internal static core. I.e., its clocktiming can be reduced to 0 MHz, so that its consumption of power is nearly 0 mW. RapidCAD: a 2-pieced chip, pincompatible to 386DX and 387DX, but containing 486 structures 80486DX: the standard 486 with internal copro and 8k cache 80486SX: same version without copro 80486SL: power-saving version of the 486SX, comparable to the 386SL 80486DX/2: an 486DX with internal clockdoubler 80486SX/J: an 80486SX with only 16 bit datapath 80486DX/4: an 486DX with tripple internal speed and 16k cache Pentium: the standard Pentium, with 60, 66 or 100,120,150,166,200 MHz PentiumPro:next generation of CPUs, now with 256 or 512k L2-cache shipped on the chip. Clocks at 150,180,200,233 MHz PentiumMMX:improved Pentium with some new commands for faster multimedia-processing. Has 32k internal cache. Needs 2.8V Pentium 2: next generation of chip. Uses "Slot 1" and does not fit in any older mainboard. Clocks at 233,266,300 and 333 MHz. Cyrix: Cx486DLC: an 386DX-pincompatible chip with 1k int. cache Cx486SLC: an 386SX-pincompatible chip with 1k int. cache Cx486S: an 486SX-pincompatible chip with 2k int. cache in some literature called M6 Cx486DX: an 486DX-pincompatible chip with 8k int. cache and copro in some literature called M7 Cx486DX/2: an 80486DX/2 clone Cx486DX/4: an 80486DX/4 clone with WriteBack features Cx5x86: chip with 486 pinout, internal optimations and 16k L1-cache 100 & 120 MHz versions availiable Cx6x86: chip with Pentium-pinout, at same clock speed slightly faster than the Pentium. Shipped with this names: 6x86 P120+ runs at 100 MHz, board 50 MHz 6x86 P133+ runs at 110 MHz, board 55 MHz 6x86 P150+ runs at 120 MHz, board 60 MHz 6x86 P166+ runs at 133 MHz, board 66 MHz 6x86 P200+ runs at 150 MHz, board 75 MHz Cx6x86MX: lastest chip from Cyrix for socket 7 /w 64k cache and MMX support. Needs 2.8V see below: Negate-Lock Pin IBM: 486SLC: an 486SX-compatible chip /w 16 bit datapath, but 16k internal cache 486BL: IBMs 'Blue-Lightning', /w internal clockdoubbler or -trippler. Only 16 bit datapath. NexGen: 586: a 5th generation CPU, like the Pentium, with 32k internal Cache, but at this time without mathematical coprocessor. Texas Instruments: TI486SXL: an Cx486DLC compatible chip with 8k int. cache TI486DX/4: an 80486DX/4 clone with WriteBack features UMC: UMC U5S: an 486SX-pincompatible chip, slightly faster than this UMC U5D: an 486DX-pincompatible chip, slightly faster than this Since mid 1993 Intel ships their 486 CPU with some internal enhancements like power-saving structures. These chips (sometimes called 486-S) do support the CPUID command, like the pentium. On such chips CONFIG gives a second line of CPU-information and tells chip-model-number and revision-level. CPUs by Cyrix and AMD do not support the CPUID command at this time. The revision-level of Cyrix's CPUs can be determinated in another way. RAM-Access: Tested here is whether the computer accesses memory:- a) in normal mode b) in Page-Mode, that is within a small page fast and outside a page slower (with waitstates). This makes possible the use of slower, cheaper RAMs at high clock frequencies. c) through a processor cache (80386+) Tries to destinguish between frist and second level cache of the cpu. L2-Level-Typ: On some mainboards the type of L2-SRAM is shown: Dual-Bank-Pipeline-Burst, Pipeline-Burst, Synchron-Burst and Asynchon-cache-types. Main Memory: Total amount of memory and amount of free memory. Extended Mem: Memory above 1 MB (only on ATs). The amount of extended memory still free is obtained from a XMS driver if used, otherwise through Int 15h. Expanded Mem: Expanded memory to LIM specification (in XTs oder ATs). This sort of memory extension can be used by many programs, and for this reason most memory managers for 386 computers change extended memory through software into expanded memory. In this case the amount of expanded memory is contained within the amount of extended memory. Graphics card 1: CGA, MGA, Hercules, EGA, and VGA video adapters are recognised. The BIOS of EGA and VGA cards are searched as above for a possible manufacturer's identity. VGA cards are tested, whether they allow 8 or 16 bit access. This is normally immediately reflected in the speed of the card. Thus even in the fastest IBM PS/2 models, the maximum video throughput is only 500kB/s, because of the 8 bit bus. A 16 bit bus card with a Tseng ET4000 chip reaches a throughput of over 2000kB/s. VGA Chip-set: CONFIG attempts to identify the chip-set of any Super VGA card which may be present. The following chip-sets can be recognised:- ATI, NCR, Trident, Video 7, Genoa, Paradise, Chips & Technologies, Above, OAK Technology, Tseng, ZyMOS, Cirrus, Ahead, Yamaha, S3, Matrox, ARK EGA/VGA-BIOS: Any further available information about the BIOS of the installed graphics card will be displayed here (only for ATI, TRIDENT, AHEAD, TSENG, GEMINI und some OAK cards). Graphics card 2: If an additional monochrome graphics card should be present, this will be displayed here NPU: Intel 8087, 80287, 80387, IIT 80287, 80387 and software coprocessor emulators can be identified. I should like to thank Norbert Juffa, author of COMPTEST, who kindly put his NPU-detection-routines at my disposal. So CONFIG detects now NPUs from Cyrix, ULSI among others as well. Game card: CONFIG will attempt to identify any Joystick port which is present. Unfortunately the identification for game cards is not standardised and other computer test programs may come to different conclusions. Generally it can be assumed, if CONFIG says a game port is present, then one is definitely present. If CONFIG says no game port is present, then "probably" none is present. Floppy drives: The number and the type of floppy drives present. IO Ports: The number of parallel and serial ports installed. HD: The harddisk's size and parameters are displayed. Due to the two different ways of defining 'megabyte' your harddisk-capacity can be calculated in two different ways: after calculating the number of bytes in the formula heads*sectors*cylinder*512-bytes-per-sector you may get the result in the unit 'megabyte' by dividing either by 1024*1024 (like in the BIOS of the computer does) or by 1000*1000 (like the producers of harddisks do). Example: the harddisk Conner CFA540A has 504 MB according to the first method of calculation and 540 MB according to the second. CONFIG offers the possibilty to choose by yourself the calculation method by entering the value of your choice (1000 or 1024) in the CONFIG.INI file's switch KILOBYTE. The Window HARDWARE 2: ====================== Here is checked whether the main BIOS can support an extended keyboard (i.e. with the extra F11 and F12 function keys), and whether such a keyboard is connected UART-Chips: Here is shown which type of chip is installed on the serial interface (8250, 16450, 16550, 16550A), and the current port settings. SCSI-Controller: The manufacturer of any installed SCSI adapter is shown, together with the start address for the controller ROM PCMCIA-BIOS: CONFIG tests if the computer has BIOS-routines to boot from PCMCIA cards. These are creditcard-sized plug-in-cards, mainly used for the enhancement of laptops, e.g. modems, harddisks, additional RAM. Sound Cards: Soundblaster, Adlib and Roland cards are searched for. Should this test collide with other hardware (Network adaptors for example), it can be disabled in the CONFIG.INI. Soundboards with AZTECH chipset are recognized. CD-ROM: Whether a CD-ROM drive is connected, and which version of the driver is in use. IDE Harddisks: If installed, the name, cache-size, version of controller and serial number of the IDE-harddisk are shown. Furthermore you get a list of the socalled 'Enhanced IDE-captability' which consists in these three points: LBA: Does the harddisc allow a 'Logical-Block-Adressing'? This is important to break the 540 MB barrier of harddisc-sizes. DMA: Is the disk able to send data via 'Direct-Memory-Access'? Adv.PIO: Does the disc support the 'Advanced PIO Mode 3'? This means that commands and data can be transferred or read from the harddiscs in cycle-times of 180 nano-seconds. Slower harddiscs support the PIO mode 2 (300 ns) or the PIO mode 1 (600 ns). These tests may cause problems on some non-IDE-harddiscs, so you can disable them by setting the switch ATBUSINFO=NO in the .INI file. The Window SOFTWARE: ==================== DOS-Version: The current DOS version is displayed. Novell DOS should be recognised. In most cases the language version should also be displayed (english, german or french). For DOS 5 will be noted whether it is currently loaded into the HMA (high memory area). If DOS has been started from an OS/2 DOS-Box, this will also be recognised. The DOS-Box of Win95 reports a DOS version 7. Networks: Is an MS-NetBIOS compatible network installed? In this case the network name for the computer will be displayed. Novell networks will be recognised. Mouse present: Microsoft, Genius, Logitech, Agiler, Reis-Ware, Unitron, und Truedox Mouse drivers can be recognised. Many mouse suppliers these days try to achieve a very high compatibility to the Microsoft original, so their drivers may be recognised as Microsoft. Note: If a program which changes the mouse interrupt has been loaded after the mouse driver (e.g. a screen saver), the mouse driver cannot be recognised. Mouse Type: If the mouse driver supports the function 36, the type (serial, bus, inport, HP-mouse) of mouse and the driver version number can be displayed EMS Driver: The type of EMS supported by the driver, and if possible the supplier name (e.g. Compaq, Toshiba...) and the pageframe address. XMS Driver: The XMS version supported by the driver, and the internal version number of the driver. DPMI Server: The versionnumber of the 'DOS Protected Mode Interface', an additional extended memory standard. DPMS Server: The versionnumber of Novell's 'DOS Protected Mode Services', yet another extended memory standard. APM-Funktionen: Can 'Advanced Power Managment' functions be found? These are BIOS routines to reduce the power consumption on notebooks. VESA-PM: This is another standard on saving electrical power. Is such a driver installed and which version-number does he have? Sofware Disk-Cache: The following can be recognised: Norton-Cache (V5 & V6), Smartdrive, IBMCACHE, Compaq-Cache, QCACHE, HyperCache, PC-Cache, NWCache. If problems should occur, the test for these programs can be disabled with the switch SkipHDCacheTest in the .INI file. Fossil-Driver: This is a software extension of the BIOS for the serial port. A driver of this kind can be essential for the use of a high speed modem and the software which is used with it. 4DOS: 4DOS, the shareware replacement for COMMAND.COM, and its version number will be identified if loaded, as will those for NDOS, a version from Peter Norton. RAM-Disk: The following RAM disk types can be recognised: VDISK (PC-DOS und DR-DOS), RAMDRIVE (MS-DOS), 386DISK (386MAX), XPANDISK, NJRAM-Disk, SRDisk, xDISK, TurboDisk EPP-Print. BIOS: This are software-routines for driving a fast printer port regarding to the 'Enhanced Parallel Port' specifications. An EPP does contain a build- in FIFO buffer like the serial 16550, which allowes a more faster and reliabler datatransfer. Memory-Manager: The following can be recognised: Windows, DesqView, 386MAX, QEMM386, Move'em, EMM386 Window ASPI Info ================ If an ASPI driver is loaded, all connected SCSI devices are listed. ASPI meens: Adaptec Advanced SCSI Programming Interface. This offers a standard procedure to communicate with most SCSI devices from different vendors. CONFIG shows CD-ROM drives, Tapes, Scanners, their vendor names, product- names and revisionlevel. Window VESA Info ================ Most VGA cards can be programmed along the "VESA-standard". This eliminates the problem to make various special routines for each different VGA hardware eg for games. CONFIG show VESA implementation version and lists the supported modi with their resolution. The PCI Information Window ========================== If your computers is equipped with Intels PCI bus architecture, all PCI componentes are listed here. The mainboards components, as well as slot cards. CONFIG may destinguish between display adapters, multimedia cards, storage controllers, PCMCIA units and so on... Over 400 vendors of PCI components are detected from their vendor-id. This offers you the ability to proove the mainboard revision level, as well, as the slot-card's. The Window BENCHMARK: ===================== Speed relative to IBM-PC: The CPU speed relative to the Pentium 100 is measured with a loop made up of frequent machine instructions such as AND, MOV, NOT, SHR, and accessing different memory segments. This value depends directly on in the CPU type, clock speed and waitstates, and is useful as a measure of pure processing speed. The loop is small, and will fit completely in a CPU-cache, if present. The real meaning of such a value is therefore debatable. Dhrystones & Whetstones: These are well known benchmark test from the Unix world, and the versions here are implemented in Pascal. The results from the pascal and C versions are compiler-dependent and not necessarily directly comparable. The larger the resulting value the better. The test routines fit completely into an 8 kB CPU-cache. Dhrystones gives a measure of the integer processing power of the CPU, Whetstones measures the performance of the Math Co-Processor. Both test were changed frequently in the 70's and 80's and there are versions in many programming languages. The pascal versions used here are the same ones used by Norbert Juffa in his test program CTEST257. The results are not however comparable with CTEST257, because Juffa used his own run-time library for his program. VideoRAM-Throughput, Scroll, VideoWaits: The Video RAM throughput describes roughly how many characters can be written directly to the screen. This value, and the time taken to scroll the screen 1 line up, depends mostly on the speed of the video adapter, but partly also on the processor speed. The number of Video-Waits is also dependent on the CPU speed, but serves mostly as a basis for comparison with other video cards. It is not to be taken as an absolute value. With a VGA card for example, very different values will be measured depending on the selected video mode. As a general rule though, the fewer waits, the faster the card! EMS-Speed: The time measured here is that to blend in 1 (!) EMS page in the page frame. The measured value is compared with the time that this task would take on a 16MHz NEAT computer (100%). Other types of hardware EMS reach values around 90-110%, 386 software EMS (e.g. 386MAX) come in at around 70%, and 286 EMS emulators about 2%-5%. RAM Disk Speed: A file is opened, written to the RAM Disk for 1 second, closed, reread, deleted and so on repeatedly. From this the throughput capability of the RAM disk is calculated. Run your RAM Disk first in Extended Memory then in Expanded Memory, and see the difference! The drive letter for the RAM Disk will be automatically recognised if possible, but can be specified in the .INI file if necessary. DOS-Disk-Speed: Here, a file is opened, written for 4 seconds to the disk, closed, reread, deleted and so on repeatedly. From this the throughput capability of this DOS Disk is calculated. The effect of caches can clearly be seen here. The drive to be tested can be specified in the .INI file! If no drive is specified here, the current drive will be tested. Harddisk Tests: The harddisk throughput is established by means of time taken to carry out absolute write-accesses through the BIOS routines. This test must be done without any cache active, because the measured speed and the interleave factor calculation from it will be heavily distorted by an active cache. CONFIG will therefore not do this test, if it finds that a cache is indeed active. The test can be forced in spite of this with the entry FORCEHDTEST=YES in the .INI file. In the same way, the rotational speed of the harddisk can only be established, so long as no cache software is active, AND the harddisk has no hardware cache bigger than 32KB of its own. The average access time is decided from 100 random head positionings over the whole disk surface, and can vary from test to test by up to 5ms. The test can be skipped by pressing the SHIFT or CAPS-LOCK key. Some SCSI and EIDE controllers seem to ignore the BIOS command 'move head'. In this case accesstimes of 0 ms are determinated, which is not accurate. Now can set the switch MoveHeadOnly to NO in the .INI file to force CONFIG to use the similar BIOS command 'move head and read data'. But now CONFIG measures time for moving the heads AND reading one sector of data from the disks. The reading time may affect the result, so the displayed accesstimes may not be comparable with the ones reported from the standard command 'move head'. The Window Mem-Timing: ====================== Displayed here is the access speed for the different areas of memory. The speed of access to the main memory (first 640k) is defined as 1.0. It can now be compared, for example, how quick the access is to, say, the VGA BIOS at C000h, perhaps with factor 2.3. That means that accesses here need 2.3 times as long as main memory access. In addition, the throughput speed of the CPU cache memory (if present) and of the main memory will be measured. The value is given in kByte/sec. The quality of the CPU cache can seen here, as can the effect of wait states on main memory access. For comparison, values for a 386/40 Forex-Chipsatz: Cache: 38000 KB, Mem: 22000 KB The Window VGA-Timing: (registered version only!) ====================== The most significant text and graphic modi are activated, and the picture frame rate measured. At each mode switch, the PC loudspeaker should click. The test lasts 30 seconds. Standard VGA cards run in text mode at 70Hz and in graphics mode at 60Hz. At 60Hz with a light picture background a slight flickering of the screen is probably noticeable. Modern graphics cards can manage 70Hz even in graphics mode, or are even freely configurable for each mode. It can happen that the computer crashes here because there very many different graphics adaptors and a mode on one does not always match exactly a mode on another. For this reason the number of modes tested can be limited by an entry in the .INI file. Negate-Lock-Pin (registered version only!) =============== Of machines equipped with Cyrix/TI/IBM CPUs the state of the Negate-Lock pin can be enabled. With this set, previously noncachable locked cycles are executed as unlocked cycles and therefore, may be cached. This results in higher performance. You may estimate a speed increase of up to 10% on machines without L2 cache as laptops and up to 5% with 256 PB cache. To enable this, start PC-CONFIG from command-line: config nolock Demo-Mode and Auto-Log / Pro Version: ============================================ Differences Pro Version to standard Version: * detects over 230 mainboard manufacturers from AMI BIOS * detects over 70 mainboard manufacturers from Award BIOS * detects monitor typ if Vesa DDC is supported eg Hitachi CM2111ME * has batch mode and demo mode Of interest to dealers is the DEMO-MODE, by which CONFIG can be set to run for a predetermined time repeatedly through the displays HARDWARE, HARDWARE2, SOFTWARE, BENCHMARK, COMPARE and INFO. Optionally a list of your own values can be displayed for comparative testing. This is ideal for a showcase or shop window demonstration. The DEMO mode can be activated either with an entry in the .INI file or from a running CONFIG by pressing the "D" key. The length of time the demo should run can also be entered in the .INI file When testing computers it is often desirable to produce a hard copy of all important screen displays. If the switch AUTOLOG in the .INI file is set to YES, then all displays defined in the switch LOG(PROTOKOLL) will be copied automatically into the file CONFIG.XXX The following screens may be logged: Hardware 1&2, Software, Benchmark, Chips, Mem-Timing, VGA-Timing, Drivers, IRQs, Notes. Logging can also be started independently from the .INI file with a command line parameter. Simply start CONFIG with the parameter p, followed by the the desired windows (see example), and the appropriate data will be logged in the file CONFIG.XXX. For example CONFIG phsm: p is for Protokoll (log) and the hsm for windows (h)ardware, (s)oftware, and (m)em-timing. If the log should be put somewhere other than the file CONFIG.XXX, this can be given as a second parameter, for example: CONFIG phsm prn and the log will be output immediately to the printer. Demo mode and Autolog are only available in the Pro-version. Limitations: ============ -under Windows95 in a window and other multitasking environments, it is not possible to make short term time measurements, which makes benchmark tests and the like impossible. -under DR-DOS 6.0 EMM386, the speed measurement test for extended memory causes privilege errors. The switch TESTEXTMEM must therefore be set to OFF -PC-Cache V5.x is recognised as Multisoft QCache -There are problems with more than ONE continuous area HI-DOS -Some computers slow down their clock frequency when a floppy drive is running. CONFIG can usually recognise when it has been started from a floppy and waits for the drive to come to rest. However with some Compaq computers this recognition does not work, and for this reason the displayed value for the clock speed is wrong. -If ALL resident software is loaded in HI-DOS, this causes problems. -CONFIG cannot find RAMdisks loaded high under QEMM. -On some computers (e.g. IBM XT/286) there are problems with establishing the harddisk access times. What to do in case of problems: =============================== CONFIG is programmed at low level, close to hardware. For this reason, crashes must be reckoned with. Recognition of the Chip-Set on the main board is sometimes problematical. This test can be skipped by pressing the SCROLL-LOCK key, or by setting the switch TESTBOARD in the CONFIG.INI file. Should CONFIG still crash before the windows appear on the screen, start CONFIG with the command line parameter "log". In this case a file CONFIG.LOG will be opened on the current drive, in which all the tests will be logged. The last test logged is then the one causing the crash. It may be possible to skip this problem area with an appropriate entry in the .INI file. If you should discover bugs in the program, or other problems, please store the current screen contents in a file by pressing F10, and send me this file together with your comments AND your version number of CONFIG AND the date of your CONFIG.EXE file. I will then try to fix the problem. Errors in 80386-Processors: =========================== To my knowledge, INTEL overlooked at least four errors (bugs) in the production of the 80386 processor: 1) Early versions could not switch back to the protected mode from the real mode 2) Early versions did not carry out 32 bit multiplication properly. 3) Early versions incremented the EDI Register after a STOSB instruction incorrectly from 0000FFFFh to 00000000h, instead of to 00010000h! 4) The POPAD instruction did not restore the EAX register correctly under certain conditions. Whereas the bugs 1-3 were very soon corrected (they only apply to 16 MHz versions anyway), bug 4 was only discovered around the middle of 1990, and nearly all versions of the 386DX and 386SX from Intel and AMD to date (Jan 91) still have the error. The very newest versions, at least from Intel, have been corrected. The bug is however now well known to programmers and the instruction used with appropriate caution. CONFIG tests for the bugs 2-4. Pentium Bug =========== The Intel Pentium was found to have a buggy floating-point division command. Intel will replace your faulty cpu on request. See various articles in Dec-94 or Jan-95 computer-magazines. Literature: =========== CONFIG is based on various sources, among others: 1 - PC Intern Systemprogrammierung, Michael Tischer, Data Becker Verlag 2 - PC-Referenz für Programmierer, Thom Hogan, Systhema Verlag 3 - Assorted issues of the german magazine c't, Heise Verlag 4 - NEAT-P9 System Board Technical Reference Manual 5 - Programmers Technical Referenz for MS-DOS and the IBM PC, Dave Williams 6 - The Interrupt List, Ralf Brown ua 7 - INFOPLUS.PAS, Andrew Rossman & Steve Grant 8 - The HIMEM-Specifications from Microsoft 9 - the sourcecode from FRACTINT 10 - The IBM PS2 Technical Reference Manual The publications 5-9 are in the public domain and available in the SIMTEL20 PD-collection.
