Subject: VT82C693A/694x and ripping audio CDs

my system:

debian unstable
kernel 2.4.18
ABIT VH6 II motherboard with VT82C693A/694x [Apollo PRO133x]
hdc: FX810T4, ATAPI CD/DVD-ROM drive
hde: TDK CDRW321040B, ATAPI CD/DVD-ROM drive
card 00:09.0 SCSI storage controller: Artop Electronic Corp ATP865
(rev 02)

(the SCSI storage is really PCI IDE card)

many of you are probably aware that it is a common problem for
VT82C693A/694x based MBs not to be able to rip audio CDs under linux
(usual message is 'lost interrupt').

I have heard that updating the BIOS might help in some cases so I
tried that and here's what happened (_few_ related problems listed
below).

-----------------------------------------------------------
fun with PCI DIE card
-----------------------------------------------------------

during boot there is strange message when probing PCI IDE card (STSTUS
instead of ALTSTATUS error message):

-----------------------------------------------------------
even more fun with usb
-----------------------------------------------------------

USB didn't work before because it is on the same interrupt as PCI IDE
card but this time I get:

at least I assume it's usb, when I disable usb in BIOS setup it works
(that why I am able to write this email:-)

-----------------------------------------------------------
on board ide and cdrom ripping
-----------------------------------------------------------

cd ripping still does not work but I get quite different messages, no
'lost interrupt' but:

Aug 21 23:52:38 localhost kernel: hdc: packet command error: status=0x51
{ DriveReady SeekComplete Error }

was:
Aug 21 23:52:38 localhost kernel: "be 04 00 00 09 01 00 00 08 f8 00 00
"

this set of messages is repeated as long as I try to rip CD.

BTW ripping on the other CDROM (/dev/hde, on PCI IDE card) still works
OK.

any advices on any of above:

- is it possible to make cd ripping work?
- is it possible to make USB work even if it shares interrupt with PCI
IDE card?
- any ideas why I'm getting ALTSTATUS message now (it wasn't there
before)

TIA

I am not sure how ACard contollers behave under ATAPI.
You will have better data security if you boot off the ACard and run ATAPI
of VIA.

what do you mean by ACard? If you mean the PCI IDE card (ATP865 below)
- why would I boot off it? I am booting from harddrive.

I have no problems with ATAPI, to have CDROM on PCI IDE card is the
only option, if it's on the VIA onboard IDE the audio cd ripping does
not work (see the error while trying to rip using /dev/hdc which is
cdrom on on board IDE).
