[Isaksson]

i have installed a 3.1rom in my a500
i hope to get my scsi hd (IVS Trumpcard with 40mb quantum) to work. first hdtoolbox didnt find my scsi controller after changing scsi.device to ivs_scsi.device according to the manual the program finds the disk, but after preparing/partitioning (low level format takes about 2 sek.is that normal???) the hard disk i get no dh0:?
in my workbench, how to salv this problem? help

is it possible to connect newer hd drive with adapter

the dh0:? dont show up on workbech after setting the drive up, i dont think hdtoolbox is formating the drive.
when i am jusing the orginal software that came with the drive the low level format takes about 3-5 min but i dont get any dh0:? :-?
