Title: NSDPatch
Post by: orange on June 13, 2005, 11:31:19 AM

I would like to use 9Gb SCSI HDD with a2091 (ROM7) and PFS3.
Is NSDPatch necessary for it ?

I have seen some posts but they were about Phase5 scsi, but not a2091. Unfortunately, it seems impossible to find ALL information about >4Gb in one place.

Not if using pfs3 as you can use its direct scsi features to overcome the 4GB limit. Ideally the boot partition should be <4GB and use rest for programs/data.

The problem is that I get "out of memory" when going past 4Gb.
probably a2091 doesnt support direct scsi that PFS does. BTW, CPU is 68000, so SFS wont work..


I want to have two partitions: System 1Gb+work 3,3Gb

Has anyone managed to format >4Gb on A2091?

EDIT: I was wrong; A2091 works perfectly with directSCSI version of PFS3, I've just tried and everything is fine  :-)

BTW, is there any speed difference between directscsi and ordinary version on 68000?
