Big config file. Which options do you choose when LH fails?

just from looking at the files, I would say that mscdex is only loaded for configuration CMC, which is conventional memory + cdrom + mouse. Not even himem is loaded.

Seems pretty obvious why it's not loading high then.

Actually, MSCDEX gets loaded when XMC, EMC, CMC or PRI are selected. It gets loaded into upper memory if there is enough UMB available (which is the real problem).

EMC

I see that only B000-B7FF is used for UMB which is too small to fit a decent amount of TSRs. Replace that X=B000-C7FF with I=D000-EFFF at least, it should give you plenty of UMB.

right, brainfart, forgot that whatever comes first runs through what lies below.

Does the lh mscdex work with PRI2 ?

ps. I personally like to use INSTALLHIGH in config sys

Do you need EMS in every config?
If not, replace RAM by NOEMS in your CONFIG.SYS' EMM386 line(s).
Then you have 64k more UMB.

Yes it does ! with NOEMS it does load high

with the EMC you have

Upper 59,952 34,224 25,728

How many UMB do you have when using the EM configuration ?

if you have more you might want to try adding the HIGHSCAN option to the emm386 commandline in the EMC section

also could you expand more on the expansion cards you have in your computer? SCSI, lan bootrom, ... ?

ps.
another thing to try would be loading these

LH C:\CTCM\CTCM.EXE LH C:\SB16\AWEUTIL.COM /S LH C:\SB16\MIXERSET.EXE /P /Q LH C:\SOFTMPU\SOFTMPU.EXE /mpu:330 /sb:220 /irq:5 […]

LH C:\CTCM\CTCM.EXE
LH C:\SB16\AWEUTIL.COM /S
LH C:\SB16\MIXERSET.EXE /P /Q
LH C:\SOFTMPU\SOFTMPU.EXE /mpu:330 /sb:220 /irq:5

after :C
hopefully ensuring that the largest free umb gets used for loading mscdex, which i'm guessing will be the 32k of the mda space (I=B000-B7FF).

CTCM and MIXERSET are configuration utilities and not TSR-s. So they do not need to be loaded high.

I am aroused about any X86 motherboard that has full functional ISA slot. I think i have problem. Not really into that original (Turbo) XT,286,386 and CGA/EGA stuff. So just a DOS nut.
PS. If I upload RAR, it is a 16-bit DOS RAR Version 2.50.

^ Yep, sometimes these programs get confused as TSRs. AWEUTIL with the /S command line switch will only initialize the EMU8K without getting it loaded as TSR for MPU-401 emulation, making LH unnecessary. It is harmless though.

I solved it by adding "/Q " in himem.sys and additional address "I=C800-EFFF" in emm386.exe . Now mscdex are in upper memory.
