Tried the CF adapter on the Sonnet ATA 133 card and couldn’t get the 9600 to boot. So I decided to remove the ATA 133 card and try the ATA 100 card with CF in slot one. It did boot slightly faster there. Since I have boot times, with the same 9.2.2 system copied over to all the drives.

18gb on the built-in SCSI boots in 115 sec

80gb on Sonnet ATA 133 in slot 1 boots in 94 sec

4gb CF on Sonnet ATA 100 in slot 1 boots in 83 sec

Currently has 400mhz G3 with maxed out RAM
