Hi CLS2086
The flash is the same for both SCSI and no SCSI versions of the blizzard.
If you have the 3.1 roms installed there is a ~30 second delay before boot whilst the system waits for response from the IDE bus
I've found there is a longer delay with the Grex flashrom than with the bvision flashrom installed.
How are you powering your system? AT/ATX psu, Amiga 'brick', Goliath, or some other way?
Regards
Rich
