Either 4 1M SIMMs or 2 4M SIMMs. They can be either 8- or 9-bit.
Set the jumpers accordingly.

Set the drive to SCSI-ID 0 and set the "last disk" bit in the
GVP Faaastprep. It makes the controller stop the disk scan
to that disk. You just have to remember to undo the change when
you add drives (or make the old drive the last ID).

I vaguely remember having 1.98g. Yep. That's it.

I am not totally certain, but you CAN use Commodore's HDToolBox
also. Note that if the Last Disk bit is set, the GVP controller
won't find the extra drives at all, but e.g. A3000 controller
will. GVP needs a reboot after resetting the last disk bit.

I also have a GVP bootdisk, which is used for a 1.2 machine.
(Boot from floppy, add HD's, then continue boot from there.)
