[NTLUG:Discuss] Via Chipset

[Gorwood, Steve]

I know that the via chipset problem with a sb live card was installed
was corrected with a BIOS change.

My understanding was that the 2.4 kernal was shipped with options set
such that dma was disabled when the via chipset was detected.  Did you
change this option back to enable dma?

My question has to do with whether anyone checked that the sound blaster
bug was the same bug as they were seeing with 2.4 kernal or is there still
another bug that no one understands?

Regards,
Steven Gorwood

AFAIK, they identified the bug and corrected it in 2.4.3. because that is my
exact setup kt133 with an SBLIVE and i have seen no corruption
