Hi there,
I hope this isn't a FAQ, or has been discussed over and over again.
I recently bought a Sparc IPC with a QIC 150 ARCHIVE Viper tape-drive
and tried to hook up an SCSI CD-ROM from Toshiba to it, with the following
results.

the stuff in between the '********' are the commands I tried. I had a look 
at st.c and patched it so that my tape-drive is recognized as one of the
rogue drives (i.e. I replaced "VIPER 150 21247" with "VIPER 150  21531", with
the result that it comes up with "st0 at scsibus0: rogue, ...") to no effect.
After mounting a CD-ROM I can "ls" the contents, but as soon as I try to
copy something, I get a "panic: pagemove 1". BTW is only part of the keyboard
supported ? no cursor keys, etc. supported in console-mode ?
I'm quite new to NetBSD (come from linux) and got the IPC up and running fine
under SunOS 4.1.3, but NetBSD has been real difficult.
Hoping for help
CU Chris.
PS: if more information is needed, just ask :)
