Subject: Getting an optical drive to work
Sender: owner-questions@FreeBSD.ORG
Precedence: bulk

Hi,

I have FreeBSD on a Gateway machine, and am trying to get a SCSI
 optical drive to work. At boot time, the device is found and
 recognised, but it does not seem to assign it to any any of the
 special files in /dev. Does anybody have any hints as to how to
 get this to work?

The pertinent part of the boot messages follows:

  ahc0 <Adaptec 294X SCSI host adapter> rev 0 int a irq 9 on pci0:6
  ahc0: reading board settings
  ahc0: 294x Single Channel, SCSI Id=7, aic7870, 16 SCBs
  ahc0: Downloading Sequencer Program...Done
  ahc0: Probing channel A
  ahc0 waiting for scsi devices to settle
  ahc0: target 0 synchronous at 10.0MB/s, offset = 0x8
  (ahc0:0:0): "COMPAQ C2490A 3184" type 0 fixed SCSI 2
  sd0(ahc0:0:0): Direct-Access 2006MB (4110000 512 byte sectors)
  ahc0: target 2 synchronous at 4.4MB/s, offset = 0x8
  (ahc0:2:0): "FUJITSU M2266S-1024 0014" type 0 fixed SCSI 1
  sd1(ahc0:2:0): Direct-Access 1087MB (1113504 1024 byte sectors)
  ahc0: target 6 synchronous at 5.0MB/s, offset = 0x8
  (ahc0:6:0): "FUJITSU M2512A 1314" type 7 removable SCSI 2
  uk0(ahc0:6:0): Unknown

The optical is the Fuji M2512A found, and is a 230MB capacity
removable optical.

Thanks for any help.
