Installation via 64bit Dual Core AMD 6000 / SATA HDD/DVD/ - Prob with /dev/cdrom detection

Hello I have been reading a bit about the problem with detecting SATA drives and happen to have the same problem I believe. It boots the kernel ok, but rejects the SATA DVD drive as being present. I assume with Debian, the first optical drive is: /dev/sr0 with hard drives starting at /dev/sd(a), etc. When I do a "ls /dev/ | more", I get the following that MIGHT be the one: /dev/discs /dev/scsi /dev/sda ---> /dev/scsi/host0/bus0/target0/lun0/disc /dev/sda1 --> /dev/scsi/host0/bus0/target0/lun0/part1 /dev/sda2 --> /dev/scsi/host0/bus0/target0/lun0/part2 /dev/sda5 --> /dev/scsi/host0/bus0/target0/lun0/part5 /dev/sda6 --> /dev/scsi/host0/bus0/target0/lun0/part6 /dev/sda7 --> /dev/scsi/host0/bus0/target0/lun0/part7 /dev/sda8 --> /dev/scsi/host0/bus0/target0/lun0/part8 /dev/sda9 --> /dev/scsi/host0/bus0/target0/lun0/part9 I can mount a few of them while during the install, but cannot "CD" in to the partitions within...1...9 My BIOS has options to emulate the SATA DEV via the following: IDE AHCI Linux AHCI I can also "umount" the disc while in the install mode and thus get an error saying it cannot load the config file, so I know I can access the DVD that way. Re-mounting the DVD allows the installer to work again Does anyone have any ideas on how to solve this? Is there a specific command I can pass to the kernel using F1 upon start-up or other?
