- Hi there, all of you
-
-
- I wrote a program that I want to share with you...
-
- SHOW.EXE is a program that shows just about all about the running DOS and
- hardware. It is just like peeking around in your PC using a small
- multi-point small flashlight...
-
- At the end of this 'story' there is a list of features that shows what can be
- 'lightened' with this program.
- I suggest that you try (to show the power of SHOW :-) ) running SHOW.EXE
- from within a MAKEFILE or even a second COMMAND.COM etc.
-
- It will reveal all these nice things about DOS that no one wanted to tell
- you, but you always suspected to be there, someway or another...
-
- In fact, the whole program (at least the DOS specific parts of it) is a
- collection of research within DOS, reading (ofcourse) the interrupt list
- available on NeWS, retries, retries, and lots of coffee...
-
-
-
-
-
- Features include :
- - HELP for all available flashlights
- - Hardware check
- - CPU range 8086, 8088, NEC V[23]0, 80186, 80188, 80286, 80386.
- - NDP range 8087, 80287, 80387
- - Speed calculation (CPU/NDP)
- - Hardware (disks/IO-ports) recognized by standard BIOS
- - Videocard range CGA, Hercules, EGA, (VGA)
- - Extended Memory sizes (AT and up only)
- - Expanded Memory (LIM) sizes
-
- - DOS internals
- - System information
- device chain information, last logical drive, DOS buffers etc.
- - Current directory paths including some obscure drive status and ID
- - Drive parameter blocks
- - Memory control blocks and their usage by all TSR programs and
- their environment(s)
- - Memory usage (memory map) (TSR/DOS) (extended with PSP-info)
- and their interrupt usage
- - BUFFERS usage (CONFIG.SYS BUFFERS=), buffer status (i.e. not flushed)
- and to which drive/sector combination it is set
- - FILE usage (CONFIG.SYS FILES=) and their access rights. The handle
- part in this case is something hidden to me...
- - Device chain list including attribute bits
- - Detailed disk information (FAT-Space etc).
-
- - BIOS
- - Interrupt vector contents (text info about interrupt usage)
-
-
- Ofcourse, this program may be used freely on a non-commercial base.
-
- Hoping, you like it...
