noooo..... it doesn't see the real drive at all, all it sees is the virtual drive. > When I try to mount the cd with "mount -t > CD9660 -r /dev/cd0a /mnt/cdrom" I get the error "no media present" > although there is a CD in the drive. Anyone know what gives with CD > drive not working as expected on the R900? dmesg below.

Take a look in the system BIOS, there may be some knobs to twist for the on-board SATA interface. IF it is there, the one I might try would be switching the interface from IDE to AHCI mode -- I've seen some machines with AHCI support that have pathetic IDE operation. You may also wish to upgrade the BIOS. Why not, that's what Dell would tell you to do. :) Wouldn't hurt trying -current on it, either. > I was trying rebuilt the kernel and binaries in hopes of making a > patched version of 5.5 stable to load on an APU.1C A process that > doesn't take too long to do on an R900. probably takes longer to boot the machine than to build a kernel. :-/ > Stan > > > OpenBSD 5.5 (GENERIC.MP) #0: Thu Sep 4 12:40:01 CDT 2014 > r...@test.test.net:/usr/src/sys/arch/amd64/compile/GENERIC.MP ... > cd0 at scsibus1 targ 1 lun 0: <Dell, Virtual CDROM, 123> SCSI0 5/cdrom > removable serial.413c00011028_123456 > umass1 at uhub5 port 2 configuration 1 interface 1 "DELL INC.
