I think to remember, that I had removed all plug-in cards back then, to
make sure that no other card was interfering IRQ-wise, but it didn't
make a difference.
But just to be certain, I can try it again on the next occasion.

I'm curious though, to find out, how Doug's EarlyMemInit=0 advice is
turning out, because that is something I hadn't tried before

My thought is that the USB Controller drivers are "built to share" - you
can have several IRQs free it seems but USB Controllers always seem to
be sharing with something.

Here the Hardware "Manager" shows that my 2 USB Controllers (1*ehci,
1*ohci) are sharing despite unused IRQs 4 and 8 - offhand I think I have
the BIOS set to Reserve 3, 5 and 7 as mentioned in ACPI docs.


What driver package are you using for the CMI8738? If not a reasonably
recent build of uniaud maybe you ought to look into an update there.

Rüdiger Ihle's CMedia-CM8738_V0.20.zip from June 2005, using cmpci32kee.sys



No disrespect meant to Rüdiger but maybe the driver simply does not share well.

I think you probably need to test that by uninstalling that driver and trying a recent Uniaud package.

Not sure about "EarlyMemInit=0"...

I have the config.sys line
EARLYMEMINIT=TRUE

I suspect the opposite is either no line or a REM at the start of it
rather than EarlyMemInit=0

IIRC, then either Mike K. or Scott G. said at some point, that kernel
statements in Config.sys with the latest 14.10x ones can now be either:
0/1, true/false. or on/off.

Just a thought: What is the Controller driver load order in use there?

If BASEDEV=USBEHCD.SYS is the 1st Controller line change it so that it
is after other controllers as in this order:-

BASEDEV=USBUHCD.SYS
BASEDEV=USBOHCD.SYS
BASEDEV=USBEHCD.SYS

That is the order I already had it, according to IBM's USB-ReadMe (here
w/o the unnecessary USBOHCD.SYS)
.
