Yes you are right, I found the HP 735 Hardware manual on the openpa
Webside and there i found that the wide-scsi connector is just for HVD

Do you know if any HVD disk is detected by the hp or are there just some
special disks for the hp ?

No linux/parisc isn`t working with FWD , I suppose, I run my HP still
under HP-UX, i have another hp 735/99 on which I want to install linux
on it, but there i have se disks in it, for now I'm running linux/parisc
only on a 715/75 with an older version of linux/parisc (the one without
hil mouse support)

Thanks for your help
