HWiNFO is a !POWERFUL! hardware detection program. It is simple, quick and
on most systems very efficient. It "tries" to give only important information
about all the physical things in your computer so that you need not look
inside the PC to see what's there. Most routines directly access the
hardware, in order to avoid some programs which emulate non-existing computer
hardware. I have excluded all unnecessary information, such as CMOS,
Interrupts, Drivers, Partitions info and others because HWiNFO is more
hardware-oriented. I hope you don't want HWiNFO to determine your
mouse cable length or the speed of your computer fan... :-)

## Requirements ##############################################################
- cca. 500 (+40) KBytes of free system memory
Well, that's all. I hope, it will work on all machines.
## Utils #####################################################################
Along with HWiNFO, there are four utilities distributed with:
GETBIOS.COM This utility retrieves all BIOS images and saves them to
files <BIOSseg>.ROM
This program doesn't run in V86 mode in order to avoid
BIOS relocation.
GETDDC.COM This utility saves VESA Display Data Channel data to file
DDC.DAT if your video card and monitor support DDC
GETPCI.EXE This utility saves all PCI devices data into files
<VendorID><DeviceID>.PCI
GETPNPRS.EXE This utility saves resource data for all Plug-and-Play
capable devices into files PNP<CSN>.RES
These utilities are free and are designed to help me improving HWiNFO if
you send the results to me.
## Registration ##############################################################
HWiNFO is shareware, meaning that you can test the program free and check
if it is useful for you. The public (unregistered) version has all the
features as the registered version except the "Create report file" feature.
The other disadvantage is the message that HWiNFO isn't registered and that
you have to press a random key while the results are shown.
If you think you could use this program and don't want to see that stupid
message, or if you continue using it after a trial period of 30 days, you
should register. Otherwise after this period HWiNFO becomes an illegal copy
and you have to delete it (ho-ho-ho :-)).
If you decide to register, you should print out the file "REGISTER.FRM",
fill it and send to this address:
Martin Malík
Jakubovo nám. 3
811 09 Bratislava
SLOVAK REPUBLIC
EUROPE
If you include your Internet e-mail address, you will receive the
registration code via e-mail, otherwise snail mail.
Once you have obtained the nice code needed to register, put exactly the
same name, and the code into the [About|Register] menu of HWiNFO and the
current version will become registered.
Well, the Registration fee is:

## Comments... ###############################################################
The CPU ID is available only on 386+ CPUs and HWiNFO uses three ways to
obtain this ID:
Method 1 - Does Reset the CPU while A20 is Enabled.
This method works on all systems, but the Reset handler gets
control after BIOS. And some BIOSes (some newer AMI/Award BIOSes)
destroy CPU ID (EDX) and therefore this ID could be invalid.
This method is default <Enabled> in Setup section.
Method 2 - Does Reset the CPU while A20 is Disabled.
This method works only on some machines, which do have a
Fully-Terminated bus. It's the best way to obtain CPU ID, because
it gets control immediately after Reset (the BIOS can't destroy
EDX). I've found some problems with this method while running
with Norton cache.
This method is default <Disabled> in Setup section.
Method 3 - Try to use this method if your BIOS destroys CPU ID. But it works
only on systems, which do not have Main BIOS (area at 0F000:0)
Write-Protected, because it modifies it for a bit, and then
restores back. This method is on some machines the only way
to obtain CPU ID.
This method is default <Enabled> in Setup setction.
HWiNFO tries to determine CPU ID this way, via: 1. CPUID instruction
2. BIOS (INT 15h)
3. Method 2 (if Enabled)
4. Method 3
5. Method 1
If you have an UMC U5SX/SD/SLV/486DX2/SX2, Enhanced Am486DX2/DX4/DX4-WB,
AMD-K5 and above, Intel 486DX/SX/DX2 SL-Enhanced, IntelDX4, IntelSX2,
IntelDX2 W-B Enh. or Intel Pentium(R) and above, there is no need to Reset
the CPU (these CPU support CPUID instruction). The most CPUs today support
CPUID instruction.
Note: NexGen Nx586 does NOT support the CPUID instruction.
Cyrix 5x86 and 6x86 support the CPUID instruction only if CPUIDEN bit
in CCR4 register is set. HWiNFO 3.0.7+ sets this bit automatically.
Disabling "CPU ID detection via Method 1, 2 and 3" reduces your CPU detection
ability ! And if there's no other way to obtain this ID (via BIOS or CPUID
instruction), it won't identify 386SL, i386CX/EX, 486DX2, IBM 486...
and some other CPUs. Do this only if your system hangs while CPU detection.
Some BIOSes simply OVERWRITE the CPU ID (EDX) :-< ! In this case is an
invalid CPU ID displayed and the CPU problably not correctly identified.
If this problem occurs, try to use Method 3 (but your Main BIOS must be
Write-Enabled !). If it doesn't work, try to use Method 2 (but you must
have a Fully-Terminated bus !). And if HWiNFO still displays, that Method 1
was used to obtain CPU ID, not Method 2 nor 3 can obtain it.
S3 ViRGE cards seem to crash while TV Tuner test. If so, disable the
"Check TV Tuner" option in Setup.
Stacker Compression Card and 3Com EtherLink III Adapter detection routines
cause crash with some Network cards. You can disable them in the Setup
section (Stacker check is default disabled; 3Com EtherLink III detection
is enabled).
On some old motherboards are random number obtained from not used I/O ports
and this may cause invalid identification of some hardware (e.g. WSS).
I don't know how to solve this problem.
The Mainboard Chipset indentification works only on newer (≈ 1991 and above)
AMI and newer AWARD BIOSes.
HWiNFO is also able to detect: √ Intel 82420TX SATURN
Intel 82420EX ARIES
Intel 82430LX MERCURY
√ Intel 82430NX NEPTUNE
√ Intel 82430FX TRITON
√ Intel 82430HX TRITON II
√ Intel 82430VX TRITON II
√ Intel 82430MX MOBILE TRITON
√ Intel 82430TX MOBILE TRITON II
√ Intel 82440FX NATOMA
Intel 82440LX AGPset
√ Intel 82450KX/GX ORION
AMD-640(TM)
chipsets, not depending on the type of BIOS.
Fixed Disk Data Transfer rate reads data from one physical sector until 4
secconds. Some caches (like Hyperdisk; but NCACHE or SMARTDRV don't) could
cause invalid results. Also some mainboards, which have incompatible
timers could cause problems.
Fixed Disk Average Seek receives results while seeking permanently 100* from
cylinder 0 to a cylinder, which is 1/3 of the max. cylinder number. Thus some
programs could report another results if they seek to an another cylinder.
SCSI disks and some Cache programs (Hyperdisk) don't generate Seek requests,
thus the Seek and RPM result is abnormal and HWiNFO displays <N/A>.
PCMCIA detection requires Socket Services or Card Services to be installed.
If you want more info about sockets, install Card Services.
Video Throughput benchmark depends only on External CPU frequency and the
type of Video board used; e.g. 486DX-33 with the same graphics board as an
i486DX4-100 (running at 3*33 MHz) report the same Video Throughput speed !
CD-ROM benchmark requires MSCDEX.EXE (Microsoft CD-ROM Extensions) to
be installed and an inserted data CD.
Intel Pentium(R) and above CPUs do not report, that the "APIC on-chip"
feature is present. Most of them (P54C yes, but P54CQS and P54LM don't)
have an on-chip APIC, but don't report it, if it isn't supported by
external hardware.
Dhrystone benchmark tests the performance of CPU and Memory, but only in
16-bit code. And so, a 150 MHz Pentium Pro (which is designed and tuned
especially for 32-bit code) returns a rather low Dhrystone result.
So, its performance while running with 16-bit applications is comparable
to a 100 MHz Pentium P54C.
If you have an Intel 420LX/420NX/430FX/430HX/430VX/430MX/430TX, SiS 85C511
of AMD-640 chipset, HWiNFO is able to detect the type of External Cache
and its size direct from the PCI chipset registers. The possible types are:
- Synchronous Pipelined Burst Cache
- Synchronous Burst Cache
- Asynchronous SRAM Cache
- Dual-Bank Pipelined Burst Cache
HWiNFO reports the size, memory type, DRAM Read Burst Timing, DRAM Write
Burst Timing and Error Check/Correction type for each DRAM row for these
chipsets:

## Running HWiNFO under V86 Memory Managers ##################################
HWiNFO (v3.00+) is able to run in Virtual86 mode under some circumstances
(it means, under some applications, which turn the V86 mode on). But ONLY
those, which support the Windows INIT BROADCAST and handle it correct.
Such known applications are:
- Microsoft EMM386 Expanded Memory Manager
- Quarterdeck QEMM386 Expanded Memory Manager
- Qualitas 386MAX Expanded Memory Manager
- Nu-Mega Soft-ICE Debugger
.......
These applications are able to switch to Real mode when they receive the
Windows INIT BROADCAST message. But if you run HWiNFO in V86 there may
occur some problems, especially during CPU RESET (like hang, crash...).
Also some Memory Managers, which relocate BIOSes may cause misidentification
of BIOS (like QEMM386's Stealth Mode). HWiNFO works best under EMM386
(I haven't found any problems). The method of detecting CPU frequency via
TSC (Time Stamp Counter) doesn't work if V86 mode is turned on.
<<< So, I prefer runnig HWiNFO in Real Mode. >>>
HWiNFO is unable to run under Microsoft Windows and Windows95 DOS box,
Windows NT VDM and IBM OS/2, because they don't switch to Real Mode and
also manipulate Benchmark results, BIOS scan, are able to control direct
I/O operations, which can cause invalid results and Windows NT doesn't
allow 16-bit applications to directly access the disk and some hardware
routines cause problems, thus it can't be supported.
## Secondary Video Info ######################################################
RISC Graphics Processor: currently identifies only Hitachi HD63484 ACRTC
Scanning for TMS: checks for TMS340x0 processor on several ports and tries
to get vendor and device name (detection routine from
SPEA GDC drivers, I don't know if it works with other TMS
cards too)
TMS Boot EEPROM: gets info from Boot Software; this won't probably work
with other cards than SPEA (I don't know :-( )
TIGA driver: gets info from TIGA driver if it's loaded (TIGACD.EXE)
Also found as: identifies all SPEA Graphiti series cards from GDCINI.DAT
and checks for HP IGC-20 and NEC MultiSync Graphics Engine
You can obtain info such as:
e.g.: RISC Graphics Processor: Hitachi HD63484 (ACRTC)
Scanning for TMS: N/A
TMS Boot EEPROM: N/A
TIGA driver: N/A
Also found as: SPEA Graphiti Flash 1G2-HE
or: RISC Graphics Processor: N/A
Scanning for TMS: (C) SPEA Software AG HILITE1024
TMS Boot EEPROM: SPEA HiLite1024
TIGA driver: N/A
Also found as: SPEA Graphiti HiLite1024
or: RISC Graphics Processor: N/A
Scanning for TMS: <I really don't know what it'll display>
TMS Boot EEPROM: -||-
TIGA driver: HP A1083A Intelligent Graphics Controller 20
Also found as: Hewlett Packard IGC-20 A1083A
## Creating a logfile or whole report ########################################
You can create a log-file by pressing the <F2> key; it will add the results
from current screen to a file named "hwinfo.log". You can change the name of
this file by entering the .log filename you want, as a parameter to hwinfo;
e.g. "hwinfo.exe my_p7.log".
There is also a "Create report file" feature, but it's available only for
registered users. It will create automatically a complete logfile, when
you start HWiNFO using the "-r" switch. There is no need to navigate HWiNFO
through all screens.
