More sound card troubles...

[jmt at NDA.COM (John Twilley)]

Home sick from work, I did some more work on my sound card's problems.

John Saylor <jsaylor at mit.edu> suggested that I try disabling most of
my AUTOEXEC.BAT.  So let's see how that works...

I 'trimmed' it by commenting out all the sound-related parts.
However, I did not disable the CONFIG.SYS, which is supposed to do
something to the sound card.

Here are the three files -- AUTOEXEC.BAT, trimmed AUTOEXEC.BAT, and
CONFIG.SYS.

--begin AUTOEXEC.BAT--
@ECHO OFF
PROMPT $P$G
SET SOUND=A:\
SET BLASTER=A220 I7 D1 T4
SET GALAXY=A220 I7 D1 P530 K11 T6
VOLSET /V:14 /X:14 /F:14 /C:14 /L:14 /M:14 /R:L
HWSET /SBA:220 /SBDMA:1 /MSSA:530 /SBIRQ:7 /GPA:E /MSS:E
AZCAL
ECHO Type L to boot Linux
--end AUTOEXEC.BAT--

--begin trimmed AUTOEXEC.BAT--
@ECHO OFF
PROMPT $P$G
REM SET SOUND=A:\
REM SET BLASTER=A220 I7 D1 T4
REM SET GALAXY=A220 I7 D1 P530 K11 T6
REM VOLSET /V:14 /X:14 /F:14 /C:14 /L:14 /M:14 /R:L
REM HWSET /SBA:220 /SBDMA:1 /MSSA:530 /SBIRQ:7 /GPA:E /MSS:E
REM AZCAL
ECHO Type L to boot Linux
--end trimmed AUTOEXEC.BAT--

--begin CONFIG.SYS--
DEVICE=A:\EEPROM.SYS /90900001
--end CONFIG.SYS--

I then rebooted six times -- cold and warm for each of three
conditions -- from the hard drive, from the untrimmed AUTOEXEC.BAT,
and from the trimmed AUTOEXEC.BAT.  (Both kernels on the floppy and on
the hard drive are identical.)

The SBPro part works in every case _except_ cold booting from the hard
drive's kernel, implying that it depends on the CONFIG.SYS to properly
configure that part of the card.

The MSS part returns a signature _only_ when the full AUTOEXEC.BAT is
used, implying that it depends on those commands to initialize the
card.

Any comments?

Jack.
