Hi !
I booted a DN3500, with ESDI disk
I ran salvol, chuvol and calendar (the HD came from another DN3500).
OS is Aegis7-Domain/IX kernel revision 9.7.5, so no chance to connect a 
SCSI disk.
The tape streamer should work, since the capstan seems to be quite 
*perfect*, but it's only 60MB, the HD is 300+ MB.
So, how can I make a disk image ?
I thought about booting from the net DomainOS sr10 (I have a 425t and 
400t with DomainOS) and call dd from there.
May I override the normal boot from disk ?
I have to boot in service mode ?
-----
Instead of a disk image, do you think it would be better to do a 
sysbackup ?
May I connect a 150MB QIC tape to the SCSI adapter ?
-----

The ESDI ISA adapter (OMTi) works on a "standard" old PC with ISA bus ?
If yes, I could take away the whole chain controller-disk and make the 
image elsewhere ...

Thanks !
