BTW most a3000d's wont boot without some scsi drive connected because the onboard termination on many of the motherboards is set wrong.
oh another BTW dont do the _int2 patch unless you have to. that patch is only to allow cpu boards WITH scsi to operate because the a3000d cpu slot doesnt have the _int2 line that is needed to enable the scsi dma channel. a3000ts and 4000s and 4000ts have this line. 3000ds do not but most cpu cards without scsi will work perfectly without the patch.
