Yes, you need the pmap partition and I as I recall, the scratch partition
is real small and is used by the driver.
] 2) What do I set the logical size to? I can't do a mkfs on the drive
] without setting it, but I don't know what to set it to since I can't
] determine how much space the other two unix partitions take up, nor
] exactly the size of a block (I read in one place it was 512 bytes,
] and off of the mkfs command that it was 1024 bytes). Where can I
] get the block size from? I have the disk partitioned for 50megs HFS
] and 50megs A/UX.
Set the logical size to the same as the physical size.
But wait.....there's more.... What you have discovered is that there is a
problem with the rodime partitioning software. You have to set the bzb_type
of the partiton also. From dp, chose to change the partition, then pick the 'b'
option. You must do this for swap and [root&] usr partitions. At this point,
if I have not forgotten something, you should be able to mkfs.
