I can only answer you by telling you how my BIOS is setup. I have a large disk on the 1st controller set to LBA. The second controller is set to NONE! for both master and slave. However, I am running two ATAPI devices on that controller: a CDROM and a TAPE. The kernel finds them OK. You only enter things in BIOS for IDE disks on my computer. > Also, in the BIOS, should I be setting the 2nd controller to use "block" > mode or LBA? Again this refers to disk geometry. LBA refers to logical block addressing which is the way all modern large disks are addressed. It is needed to bypass the old 528MB BIOS limit for hard disks. CDROMS use a different protocol called ATAPI which stands for AT-Attached Packet Interface. Are you sure that you configured your kernel correctly? According to your previous note you are running 3.3 release so you should have something like below for your kernel config file: options "CMD640" controller wdc0 at isa? port "IO_WD1" bio irq 14 disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 controller wdc1 at isa? port "IO_WD2" bio irq 15 disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 options ATAPI # Enable ATAPI support (VERY IMPORTANT) options ATAPI_STATIC # Don't do as LKM device acd0 # ATAPI CDROM disk Maybe you should experiment around a little bit. Try choosing "none" in the entry for your 2nd controller, then make sure that your kernel supports ATAPI as above.
