So just a little more followup, for my A3000D I found this today:
1 - 3.1 HDToolBox worked with multiple slots and CF, SD and PCcard slot
(although it could not read the size of the media upon scan)
2 - Now, HDInstTool (which is more recent and updated) would only report back 'unsupported' whenever I tried the CF or SD slot. PCcard slot is fine.
I bought one of these SCSI card readers from mechy a few months ago, just got around attaching it to my A3000 with a WD -08 in it.
Also on the scsi chain are two internal drive id 0 and 1, The card reader is on the external scsi and set to id 2, I also have a external cd rom on id 3.
to get the multiple LUNS working one needs to set the access the nvram in the A3000. I used SetBatt from fred fish disk 535, Probably can get this from aminet.
Use SetBatt to turn multiple luns on. In both of my a3000s the default was multiple luns off.
I still cannot get the a3000 to autoboot of the CF card. I have to use mounter (comes with 3.9) or SCSImount to get the partitions to mount.
someone mentioned needing to have the card reader set as and internal device to get it to card reader to autoboot. This should really not matter, but I have seen stranger things with scsi devices. I would love to get my a3000 to autoboot with the card reader,
I have two gvp scsi cards, a trumpcard, and a dataflyer. I will see if can get these to work with the card reader.
