Alright, here's the deal. I've been trying to get this thing to work and, well, with my luck, I don't think it will ever happen. I have looked through the forum and have tried various things, but nothing works. (I know, that's quite vague, but give me a minute!) Here's what I have:
RedHat 7.3, HP CD-Writer Plus 9300 series, Prestonia Pentium IV (Xeon) @ 2GHz, 80GB, 256MB, and another CD-ROM drive installed. All I am trying to do is get X-CD-Roast to recognize the drive (hdd). My machine recognizes it at boot-up time and within Linux, but I have no idea how to enable SCSI-emulation on my machine. All of the posts I have located all have something to do with GRUB or LILO, both of which I am NOT using, nor will I (This machine is part of a rack-mount cluster which is ghosted every night, due to my Oracle Database being housed on it. Neither GRUB or LILO are compatible with the version of Symantec Ghost of which I have).
I thought it would be a simple task; installing the drive, setting it as slave, running a SCSI-Bus scan, and ripping a few CDs, but I guess I was sadly mistaken. If anybody can help, it is already greatly appreciated. Thanks.

here is the output from cdrecord from my RedHat 7.3 box with my HP 9300 when i su to root at the command prompt:

sorry, I put an answer here, but it pertained to lilo. I read on in your post, and see that it wouldn't help you.
