The 4in1 version 4.23 drivers are working fine for me:
KK266, TBird 800, 256MB, GF2MX, 45GB IBM GXP75, HP CDRW,
internal Zip 100, Bios 0415, Win98 and mandrake 8. I
had trouble with power-saving mode but new video driver
seems to work.
I'm still using the onboard sound. I was going to get a
SBLive, but then the whole SB/686B thing came up, and the
sound is good enough for me. I grabbed the latest drivers
for the sound chip from cmedia. I have not had any problems
with file corruption with the zip drive.
