#ShapeShifter questions
"Also, is there any way to get SS to use the same hd partition as my Emplant? I
select DH1 in the volume chooser, but it just tells me that it's not a DOS
disk."
Yes you can Paul, I used the Emplant partition for a few weeks with
ShapeShifter until I removed the Emplant board. What you need to use is the
Emplant's "MAC_HDSetup" program. This is the information that I got on my
ShapeShifter partition:
Device: DHN
Surfaces: 8
LoCyl: 590 HiCyl: 4895
Blocks Per Track: 63
Mac Boot Block: 297360
Drive Type: AmigaHD w/Mac Data
Bootable Partition
And this is what is set up for DeviceDisk 1 in ShapeShifter:
scsi.device Unit: 0
First Sector: 297360 (The Mac Boot Block in the above information)
Number of Sectors: 2170224 (see below for details)
Maximum transfer size: 130560 (MaxTrans for a Amiga IDE device)
To get the Number of Sectors for ShapeShifters devicedisk:
((HiCyl – LowCyl)+1) x Surfaces x BlocksPerTrack
So ((4895 – 590) + 1) x 8 x 63
4306 x 8 = 34448 x 63 = 2170224 and there you have it!
The Maximum transfer size is just the MaxTransfer setting for that particular
partition and you can get it by using HDToolBox to find out what it is
currently set at. For my IDE drive it is set for $1FE00 so in decimal that
works out to 130560.
Hope this helps you and other Emplant users that want to take ShapeShifter for
a spin but don't want to start from scratch. If you have any questions, feel
free to ask.
