I've acquired my first Intel box - something I've avoided for a
very long time, however, I figured it was about time to take a look
and a friend wanted to part with this system. The beast I got is
a dual 200 MHz Pentium Pro system, based on an Intel PR440FX
motherboard, with 128MB of RAM, Intel 10/100 FDX Ethernet, USB,
Crystal CS4236 (SoundBlaster compatible sound chip), and Adaptec
7880 Ultra-Wide-SCSI on the board.

The install from the Wasabi 1.5 CD-ROM worked great, until it came
time to boot the installed system. The GENERIC kernel hung during
probe of the Crystal CS4236 sound chip. The device claims, according
to Intel's documentation, to be both SoundBlaster and Windows Sound
System (WSS) compatible.

I put together a 1.5-release branch kernel without any ISA audio
defined it in (just like the install kernel) and that comes up to
multiuser with no problems. Then I compiled a series of kernels in
an attempt to boot something that would both recognize the device
and come all the way up (no hang). I tried:

	SB on isapnp
	SB on isa (with matching params)
	WSS on isapnp

The upshot is that SB doesn't match no matter what I try, and WSS
matches, but hangs. Here's the relevant section of autoconf output
from the no-audio kernel:

isapnp0 at isa0 port 0x279: ISA Plug 'n Play device support
isapnp0: read port 0x203
isapnp0: <CS4236  Audio, CSC0000, , WSS/SB> port 0x534/4,0x388/4,0x220/16 irq 5 drq 1,0 not configured

isapnp0: <CS4236  Audio, CSC0003, , MPU> port 0x330/2 irq 9 not configured

I'm writing here for two reasons:

1. Report a failing in the -release branch GENERIC kernel.

2. get suggestions for ways to make this work.

Please reply to me, I'm not on port-i386 (yet).

	thanks,
