[vox-tech] no dev file for newly installed HD

Tue, 4 Jun 2002 14:03:30 -0700 (PDT)

Your bootloader might be passing "hdf=3Dide-scsi" parameter.  *If* that is
the case, take the following measures:

   - If you are using LILO:

     1. Edit /etc/lilo.conf as root.
        (change the line that says "hdf=3Dide-scsi" to "hdg=3Dide-scsi")

     2. Run `lilo` as root.

   - If you are using Grub:

     1. I don't know -- I don't use Grub :)

You *may* also need to change some settings so your CD programs see the
new device name for your CD drive, but it may or may not be necessary.  It
may also depend from program to program.
