Thanks for your various thoughts so far. I'm narrowing my quest to
sorting out problems with the Warty full install for now, perhaps
fiddle with the Live CD more later.

OK! - tho there are many variants of the 390X. I've got the 2626-FOU,
(Celeron 400) ESS Solo-1 sound (ES1938/1969). And yours??

Would you try booting with your pcmcia cards removed and see if the
sound is still normal? Catch here is both my nic or wireless cards 
physically block the use my modem in 2nd pcmcia slot. There is also an 
onboard winmodem, Lucent, which I know can be made to work under Linux 
(works with Mepis live cd), so that is On The List.

My sound seems to associate with PCI device 2, and I've tried
various combinations of IRQ's with the 4 PCI devices, no improvement.
The bios default is IRQ5, so back to that now. "lspci -v" with and 
without the nic is identical, except for the nic entry. I still 
think/hope that a fix for this is a dozen keystrokes away... Just 
downloaded kernel-parameters.txt, interesting stuff.

Interesting, as my next project will likely be getting my Dlink G650
to work. Oops, I see yours is a TI chipset, mine is Atheros.

Great, that worked on both of those issues.

I've found that if "pci=noacpi" is also added, that causes the error
message to appear again.
