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 V0, 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
- 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).
- Interrupt vector contents (text info about interrupt usage)
Ofcourse, this program may be used freely on a non-commercial base.
Hoping, you like it...
