VT82C693A/694x and ripping audio CDs

[Erik Steffl]

  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 }
Aug 21 23:52:38 localhost kernel: hdc: packet command error: error=0xb0

(asc=0xbf, ascq=0x00)
Aug 21 23:52:38 localhost kernel:   The failed "Read CD" packet command
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
