I've got an HP Vectra VL-3 with a Soundblaster 16 running an IDE 4X=20
CD-ROM drive. Linux cannot see the CD-ROM drive.
Here are the particulars of the system:
P75
PCI, apparently with the buggy cmd chip
Two hard drives on the on-board IDE controller
SoundBlaster 16 w/IDE connector
Creative Labs FX400 IDE CD-ROM
An on-board IDE-CDROM connector (colored red)
The problem is that Linux won't see the CD-ROM. I cant say I understand=

the problem in it's entirety, but I've tried several things.
1) Tried booting from a slackware 2.3 bootdisk, and adding hdc=3Dcdrom an=
d=20
also hdd=3Dcdrom as boot options. CD-ROM wasn't found
2) Tried the 1.3.29 kernel, with IDE CD-ROM support. CD-ROM wasn't found.
3) Tried the 1.3.29 kernel, with the CD-ROM connected to the motherboard=

IDE CD-ROM connector (colored red) and the SoundBlaster IDE DIS jumper=20 closed (IDE disabled). This was a little closer, but it still failed.=20 Here's the the significant-looking output of dmesg:

The drive can be read fine from DOS.
I'd very much like to get this drive working. I'll provide any more=20 information that's needed about the machine. I'm only using the 1.3.29=20 kernel in the hopes that it fixes something broken in 1.2.13. My hope is=
=20
to get the CD-ROM working with 1.2.13 somehow.
I'll gladly RTFM if you tell me what M to R.
