Re: kernel 2.4.x + via-based kt266 mobo = IDE cdroms probls

[Andre Costa]

Ok, replying to my own msg just to post some updates:

it has been confirmed by me and others that downgrading AMI BIOS on our
specific mobo (MSI KT266Pro2) to v3.3 fixes the "lost interrupt" errors
with cd audio ripping. Latest BIOS is 3.7:

[http://www.msi.com.tw/program/support/bios/bos/spt_bos_detail.php?UID=28&NAME=MS-6380]

Any suggestion on how we could pressure AMI or MSI to fix this probl on
BIOS versions higher than 3.3? (or, maybe, to provide you guys some docs
explaining the changes so that Linux kernel can catch up, considering
that the probl doesn't happen on Win2k/XP?)

Best,

Andre
