In the meantime:

Ive seen many things cause these types of boot problems on g3s and g4s.

My recommendations:

disconnect all external usb, firewire..etc. devices except keyboard and mouse (don't use a hub).

disable all extensions/control panels associated with these devices.

If you are using a "stealthport" in your internal modem port...pull it out..and disable the extensions.

Leave the digi 001 card in..and leave the oms..and DAE..etc loaded.

Restart:

If you get a clean boot...then there isnothing wrong with your Digi hardware..or..the Mac hardware.

My guess is...its a usb or firewire driver.

Ive seen them...hang G3s and G4's on startup...to a grey blank screen.

If you have a 3rd party scsi card..it may be conflicting with the 001 in some way.

If your machine won't boot with extensions off..but..will boot with everything disconnected...then..you have a device problem.

By leaving the 001 hardware installed...you can add your devices back one at a time..until you find the culprit.

Again..my bet..its either a USB adapter/device...or ..one of your other PCI cards/drivers..causing this.

If you are simply getting a black screen:
have you recently installed any ram?

If so..pull the installed ram..and leave just the apple ram...and see if machine boots.(mismatched speed ram..can sometimes cause a non-boot).

Its important..to know..exactly what your machine is doing at boot..as these are the clues.....do you get a startup sound?
Is the machine black screen or grey?

etc.

Hope this helps.
