The subject line is for other people with the problem, which took me two 
days to solve.  I kept getting a kernel unusable for sound (sound.o).

CONFIG_PCI_QUIRKS=y eliminated the above problem when I compiled a kernel 
for sound and soundblaster with CONFIG_SOUND_OSS=m (used by some other 
cards besides sb) which lets you use sound.o

With QUIRKS set to N the kernel was only minimally smaller, and I could 
not use sound:  insmod:  Unresolved symbol isa_dma_bridge_buggy.

On the web I ran acros someone's comment that changing the setting on 
PC_QUIRKS after compiling a first kernel made the second kernel buggy. 
This does not seem to be exactly the case here, it is just that you need 
PCI_QUIRKS=y, at lesat for the two computers I tried sound on.

'If you have a broken BIOS, it may fail to set up the PCI bus in a correct 
or optimal fashion.  Saying Y here will correct that problem.  If your 
BIOS is fine you can say N here for a very slightly smaller kernel. If 
unsure, say Y.'   BL2 kernel said Y and I should have stayed with that.

I was able to compile a kernel that worked with sound on both computers, 
with gcc 2.95.3 from SW81 and with egcs from SW71.

I have the kernel and config files at
keesan.freeshell.org/zImage.ss and /config.ss (for scsi sound)

I removed support for math emulation and 386, for all the network file 
systems, and for ethernet cards that I do not have (I left support for 
cards needing modules 3c509, 3c59x, and apparently tulip and rtl8139 are 
supported without specifying anything but CONFIG_EISA=y which also covers 
PCI bus).  ppp is in the kernel but other features are modules.

I added scsi support for scanner (sg), CD-burner (including ide-scsi scsi 
emulation) (sr_mod and ide-scsi), and zip drive (sd_mod).  I checked and
the zip drive works.  But the kernel will work only for Adaptec PCI scsi 
cards that use module aic7xxx.o (of which I have two).  I included support 
for ppa.o (parport scsi-emulation zip drive) but not imm (later model).

I have support for sb, and hopefully also ess1370 and esssolo1 - which I 
had to fill in by hand because the config program never mentions it but I 
found it in bare.i.

I see now why steven left out scsi support (too many possible cards) and 
sound support (ditto - and it required several modules which take up 
space.  I included also lowlevel=y and awe32=m).

If anyone wants a variation of this kernel set for their own scsi card or 
sound card, I can attempt to make you a modified .config file or you can 
download mine and use it for reference and make your own.  Run make config 
anyway unless you know some other way to produce the file it produces 
(just hold down the Enter key to choose defaults).

Copy the linux-2.2.16.tar.bz2 from SW71 source CD (kernel-source) and 
bunzip2 it (get bzip2.tgz), also insmod bin86.tgz from installation CD.
untar (tar -xvf linux*tar), cd linux, make config and answer lots of 
questions (you can start with my file, hand-edit it if you are brave, and 
then go through make config hitting the enter key to accept my choices 
until you hit something you want to change - this will hopefully ensure 
you have the correct dependencies for modules).

After make config, make dep, then make zImage and in 10 min (or longer on 
a 386) you should have ./linux/arch/i386/boot/zImage.

Mine is 465K.  PPP in the kernel and the sound modules made it larger but 
I saved space on math emu and network file systems and fewer ethernet 
cards, so it is about 30K less than the BL2 kernel.

A kernel compiled for 386 without math emulation (or sound, scsi, or 
ethernet) was 404K.

I included vfat because I can mount my floppy disks without having to 
specify -t msdos that way.  (I think I formatted the floppy disks with MS 
DOS7.1 which even though we set it up as no-long-file-names on hard drive, 
appears to treat floppy disks as LFN/vfat).

I have not tried mounting one of these disks with BL3 (no vfat).

I probably did not need the IDEPCI IDADMA stuff and will remove them next 
time I compile.
