- No, no one can tell you a command that will work for sure on your machine,
- because the necssary parameters depend on which logical device your
- CD-ROM drive is. If you have no other SCSI devices besides the hard-drive
- that came inside your next, than the device will almost certainly be
- "sd1", and thus you'll usually refer to the CD-ROM as "/dev/sd1a" (or
- sometimes "/dev/rsd1a").
-
- A way to check is to watch what happens when you boot, my NeXT says:
-
- QUANTUM PD210S Rev 508D as sd0 at sc0 target 1 lun 0
- Disk Label: MyDisk
- Disk Capacity 199MB, Device Block 512 bytes
- SONY CD-ROM CDU-541 Rev 2.6a as sd1 at sc0 target 4 lun 0
- Disk Label: NeXTSTEP_3.0 ^^^------------------------- N.B.
- Disk Capacity 659MB, Device Block 2048 bytes
- Disk is Write Protected
-
- I have my NeXT always mount the NeXTSTEP_3.0 at startup, which just meant
- adding the following line to the file "/etc/fstab":
-
- /dev/sd1a /NeXTSTEP_3.0 4.3 ro,noquota,removable 0 2
-
- If I was giving these options to the mount command by hand, I guess the
- following would work:
-
- next_mach# mount -t 4.3 -o ro,noquota,removable /dev/sd1a /NeXTSTEP_3.0
-
- (Although, that might be overkill, "mount /dev/sd1a /NeXTSTEP_3.0" might
- be all that's required).
-
- If you want to eject the disk, the following should work:
-
- next_mach# umount /NeXTSTEP_3.0
- next_mach# disk -e /dev/rsd1a
-
- Finally, if you ever want to know what the "correct" parameters are for
- a disk that you can automount, look at /etc/mtab when the disk is
- automounted, at the very least, it should serve as a good starting point.
-
- Hope this helps, best regards,
-
- Richard.
