WHAT AM I? Version 5 COMPUTER INFORMATION PROGRAM BY PETER A. HYMAN 148 Tennyson Drive, Plainsboro, NJ 08536 (609) 799-2638 DESCRIPTION: WHAT AM I? is a utility program written in C and Assembler for IBM PCs and compatibles that identifies equipment contained in or attached to the PC including a complete list of all environment strings set in the DOS environment. WHAT AM I? is designed to assist computer users, managers and/or computer departments to quickly and accurately find out what's "under the hood." Since its first two releases, WHAT AM I? has been extensively re- vised. WHAT AM I? now detects specific types of CPUs and Math Coprocessors (from the 8086 to 80486, from the 8087 to Weitek 1167), video adapters, Extended Memory and XMS Driver information, Expanded Memory Driver information and Handle usage, floppy and hard disk con- figurations, ROM Bios and Extensions identification and to test for the presence of a Mouse. WHAT AM I? offers full pop-up window support for detailed information about Extended and Expanded memory usage, Disk Drive Adapters and con- figuration, ROM Bios and Bios Extensions. WHAT AM I? now has a command line option to use 43 line EGA or 50 line VGA text modes for those us- ers who need the extra screen space to display environment variables. WHAT AM I? was improved to correctly identify valid, usable disk drives (i.e. not just report the number of drives as specified by the LASTDRIVE parameter, but to poll each valid drive letter individually), and to correctly report on Extended Memory (since XMS drivers hooked INT 15h function 88h it was impossible to get the correct amount of to- tal Extended Memory, so WHAT AM I? now queries the CMOS directly). The WHAT AM I? display was updated to be more easy to read, and all large numbers use commas to separate thousands and millions. CHANGES TO VERSION 5.0 The /S parameter has been removed. WHATAMI will automatically sort en- vironment variables by default. WHATAMI incorrectly reported the number of Expanded Memory in KB. It reported Extended Memory in KB. WHATAMI incorrectly reported the XMS Driver Internal Revision Number. The entire number is reported as a HEX number, and WHATAMI reported it as decimal. Thus an XMS internal revision number of 5.12 was reported as 5.18 by WHATAMI. WHATAMI incorrectly reported an 80387 coprocessor as installed when it detected an 80486DX CPU. This has been changed to report Internal for the coprocessor type. WHAT AM I? Version 5 COMPUTER INFORMATION PROGRAM BY PETER A. HYMAN 148 Tennyson Drive, Plainsboro, NJ 08536 (609) 799-2638 CHANGES TO VERSION 5.0 (continued) WHATAMI now reports both the total free and largest available block of Upper Memory. For advanced VGA cards, WHATAMI will report "256K or More" if it de- tects 256KB or memory. Previously, WHATAMI only reported 256K. Two new F key functions have been added. [F6] will print a report of all screens to the standard print device. [F7] will print a report of all screens to a file called WHATAMI.INF in the current directory. USING WHAT AM I?: Command line syntax: WHATAMI [?|-?|/?] [/|-E] [drive[:]] WHATAMI.EXE has three optional command line arguments. If none are specified, WHAT AM I? will give system information and analyze the cur- rent disk drive. The ? or /? or -? parameter will cause help informa- tion to be displayed on the screen. The /E or -E option will force WHAT AM I? to use 43 line EGA or 50 line VGA text modes to display sys- tem information. If an EGA or VGA display adapter is not present, the program will abort with an error. The drive parameter is a letter re- questing WHAT AM I? to analyze the requested disk drive. If the drive is invalid or if there is any kind of error, it will be reported, but the program will run. WHAT AM I? will display as many environment variables as it can at the bottom of the screen. If there are more than can fit, you will be prompted to press any key to view more. Af- ter all environment variables have been viewed, you will be asked to press any key to end the program. This will allow the user to print the screen if desired using SHFT+PRTSC. (You can also use the [F6] key). INTERACTING WITH WHAT AM I?: WHAT AM I? uses pop-up and movable windows to display additional infor- mation. Function Keys 1 to 7 may be used to invoke pop up windows to display information about the following: [F1] - Help Key. Lists Valid Function keys and command line arguments. [F2] - Extended Memory Information. This window will only be displayed if Extended Memory is present AND there is an XMS (Extended Memory Specification) driver installed. The F2 window will show the driver and revision version numbers, Total Extended Memory, Free Extended Memory, the availability of the High Memory Area (HMA) and Upper Memory Blocks (UMBs). Pressing the [F2] key when there is no XMS driver will have no effect. WHAT AM I? Version 5 COMPUTER INFORMATION PROGRAM BY PETER A. HYMAN 148 Tennyson Drive, Plainsboro, NJ 08536 (609) 799-2638 INTERACTING WITH WHAT AM I? (continued): [F3] - Expanded Memory Information. This will only be displayed if Ex- panded Memory is present. The F3 window will show the Expanded Memory Version, Page Frame location, Memory status, and a list of all allocated EMS handles and their owners. There may be several pages of this information, and the PageUp or PageDn keys may be used to move through the list. At the end of the list of handles will be memory usage totals. Pressing the [F3] key when there is no Expanded Memory will have no effect. [F4] - Disk Drive Information. This window will list the physical characteristics of attached disk drives, including the number of heads, cylinders, sectors, and total size. This display reports total disk size which may include non-DOS partitions, or other logical partitions. If a device driver has been loaded to simulate a hard disk (e.g. Bernoulli boxes), they will be reported as well. [F5] - ROM Bios and Bios Extensions information. This window will show as much information as it can about any Bios which is installed in the machine. At a minimum, your system Bios will be identified. Any other Bios installed will also be reported on. This screen will only display "readable" characters from the Bios. [F6] - Print a report to the printer. [F7] - Print a report to the file WHATAMI.INF. After any window has been reviewed it may be cleared by pressing any key. It may also be moved by using the cursor keys. Windows may be superimposed by pressing another function key. If numerous windows are open, one window may be brought to the foreground by pressing its func- tion key. After all windows are cleared, pressing any key will con- tinue the WHAT AM I? program. WHAT AM I? Version 5 COMPUTER INFORMATION PROGRAM BY PETER A.

If not, this line and the next will NOT appear on the display. If an XMS driver is detected, its version number will be displayed in the V X.XX format. Total Extended Memory as reported by the CMOS will be displayed. The Total Extended Memory is not computed using INT 15H function 88H since XMS drivers hook that interrupt to report 0KB Extended Memory. FREE EXTENDED MEMORY : This line will only appear if an XMS Driver is loaded, and if so, will report the total amount of unused Extended Memory. EXPANDED MEMORY V 4.00: This line will only appear if Expanded Memory is detected in the target system. If not, this line and the next will NOT appear on the display. The Expanded Memory Version will be displayed in the V X.XX format. Total Expanded Memory will be displayed. FREE EXPANDED MEMORY : This line will only appear if Expanded Memory is detected in the target system. If not, this line will NOT appear on the display. The total amount of Free Ex- panded Memory will be displayed. DISPLAY MODE/ADAPTER : This line reports the current video mode (BW or COLOR), plus will identify the active display adapter and, if an EGA, VGA, PGA adapter is found, it will report the amount of RAM detected on the card (up to 256K).

This is due to the fact that multitasking programs can limit the amount of EXPanded memory available to a process. By re- viewing the total of EXPanded memory used by all Handles (see the bottom part of the EXPanded memory pop up window) the ac- tual total can be determined)) Total EXPanded Memory Used : The total amount of EXPanded memory used from within the current process. Free EXPanded Memory : The total amount of free EXPanded memory The lower part of the display shows each Handle's usage of EXPan- ded memory, including the Handle number, its Name (if available), the total number of Bytes of EXPanded memory it uses, and that number stated as 16KB pages and 1KB chunks.

Using Bios function 13H function 8, it retrieves informa- tion about all attached devices, including the drive type, the number of physical drive heads, Tracks or Cylinders per Disk, Sectors per Track. The Total Size is computed by the formula H * T * S * 512. The disk Size in MB/KB takes the Total Size, divides by 1024. If that re- sult is greater than 1000, the partial result is divided by 1000. The size in MB therefore, is really the size in thousands of KB. This is to remain consistent with almost all statements of disk size by other programs and manufacturers. An actual statement of MB would take the Total Size, and divide by 1024 and again by 1024. If a device driver has been loaded (e.g. a Bernoulli disk driver) which "fools" DOS into seeing another device, an asterisk will appear after the device name (e.g. Fixed Disk*) and a footnote explaining this will appear at the bottom of the disk window. In the case of Bernoullis, the total size of the device may not reflect the net size of all car- tridges. WHAT AM I? Version 5 COMPUTER INFORMATION PROGRAM BY PETER A.
