I know that this is extremely low priority but...

I have tried to boot the linux kernel from a SCSI DDS
tape (copied via dd if=Image of=/dev/rmt/0m bs=512).
The same kernel (cvs tree from today) boots
sucessfully via rbootd on my 715/33. Here is the
console log:

Should this work or is this a current limitation ?

Hi all,

thanks for all the tips. dd-ing with bs=2k made the
difference. The kernel now also boots from a SCSI DDS
tape drive (HP35480A). My first thought was to choose
the disk sector size 512 but this was wrong.
