Hi all,
I still have a problem with the netinst.iso: it seems not to boot
because of the following error, occurring when I try to boot from cdrom:

Failed to initialize.

I have already tried to boot from another workstation (with has HPPA
Linux running on since a while) but the cdrom caused the same error.
Is it a problem of the medium or what?
I have got an HP9000/C3000 workstation. I use an external CD-Rom
(SCSI.3.0                 YAMAHA  CRW8424S)
Thank you in advance

Regards
