AUTOEXEC.BAT & CONFIG.SYS Advice Needed

I am almost finished with this 486 build and am now working on the start up files. I am using Phil's DOS starter pack AUTOEXEC.BAT and CONFIG.SYS and they work really well. But I did run in to a problem when I install the drivers for the SB16 Value CT2770. I used the drivers from the VOGON's library here http://www.vogonsdrivers.com/getfile.php?file … menustate=42,35 . When I run the install for the card it installs as it should and the sound card works but I lose a lot of usable conventional memory when it is installed. Can anyone advise (I had to put a space between : and X otherwise it used a smiley)?

Here is the AUTOEXEC.BAT:

SET SOUND=C:\SB16
SET BLASTER=A220 I5 D1 H5 P330 T6
SET MIDI=SYNTH:1 MAP:E
C:\SB16\DIAGNOSE /S
C:\SB16\SB16SET /P /Q
@ECHO OFF
PROMPT $p$g
PATH C:\DOS
SET TEMP=C:\DOS
GoTo %config%
:EMC
: XMC
:CMC
LH C:\DOS\MSCDEX.EXE /D:OPTICAL
:EM
: XM
:CM
LH C:\DRIVERS\CTMOUSE.EXE /R2
:E
: X
:C

And here is the CONFIG.SYS:

[COMMON]
DEVICE=C:\SB16\DRV\CTSB16.SYS /UNIT=0 /BLASTER=A:220 I:5 D:1 H:5
DEVICE=C:\SB16\DRV\CTMMSYS.SYS
FILES=40
DOS=HIGH,UMB
REM ** FILES=30
BUFFERS=30
LASTDRIVE=H

I would just REM out the lines added by the SB16 install one at a time, check conventional memory, and check functionality. I think the two config.sys lines are the memory hogs and can be safely REM'd out.

The more I learn, the more I realize how much I don't know.

I suppose I could try that. I assume changing the the order that the lines are loaded in and/or removing some non-essential lines would help. I hoped someone here would know off the top of their head as the other way would be time consuming.

Well, you could move the two config.sys lines below DOS=HIGH,UMB and change them to DEVICEHIGH= and see if they get partially or fully loaded into upper memory. I just remember when I set up my CT2800 I went through this and came to the conclusion that only the autoexec.bat lines were needed for just playing DOS games.

edit: also try running MEMMAKER if they still are not loading into upper mem.

OK, thanks for the advice. I will tinker with it and see what I come up with. The process of this build has been a long journey. But there is now light at the end of the tunnel! I have had to overcome problems with finding a new AT PSU, mounting the power switch, mounting the AT board in an ATX case and getting the mouse serial port to work. Some of this I have posted previous threads on. Would not have got this far without VOGONS!

CTSB16.SYS and CTMMSYS.SYS aren't really very useful. They're plumbing provided for software developers to make it easier to interface with the cards, but most software implements support natively. The upshot is, your SB16 value should run with nothing resident and will work with 99.9% of the software out there.

You can always load them dynamically, too!

So, take everything sound card related out of the CONFIG.SYS and leave the lines in the AUTOEXEC.BAT?
