Search for text in environment variable

[Jack B. Pollack]

I have a backup program that runs from a Win 98 startup disk (not a DOS box
under Windows).
I need to be able to detect if it is running on Computer1 or Computer2.

Obviously, I cant read or see the NTFS hard drives to determine C1 or C2,
but there are two differences I can detect easily under DOS. A DOS mem
command reports slightly different value, and if I load oakcd.sys the CD
drive make & model numbers are different.

So unless someone has a better (easier) idea, what I would like to do is
send the output of a mem command preferably to a environment variable (would
prefer not to write it to a temp file) and then search for a specific value.

Can someone help mw with this?

Thanks

Are you able to put a file in the root of C1?

if exist c:\pc-1.txt set var=yes

I missed the NTFS bit - so you can't see the HDD.


mem /c |find "string" >nul
if not errorlevel 1 set var=c1

It isn't explicitly stated but apparently you are booting from a Windows 98 CD onto computers which have NTFS volumes, so this is a request for help
with scripting COMMAND.COM, not CMD.EXE; is that correct?

Thanks. Worked perfectly

No, sorry. When I used to do this I used a small assembler program to scan
for a signature in the ROM to distinguish the PCs, which then allowed me
to choose a NIC. These days I'd use a pciscan to detect it.

Looks like foxidrive has the answer

hdd volume serial number
english windows
dir |find "Volume Serial Number"
if "Volume Serail Number is xxxxx" == "Volume Serail Number is xxxxx" goto :xxx
if "Volume Serail Number is xxxxx" == "Volume Serail Number is xxxxx" goto :xxx

If you re-read the question, he can't access the hard disk info, as it's
NTFS

this would be closer, if the hard disks could be seen:
for /F "tokens=5 delims= " %%a in ('vol C:^|find "Volume Serial"') do if
%%a == xxxx-yyyy echo Computer1
