no beep codes. its a server, with dual pentium 2's or something its a slot A processors, its got 2 power supplies built in to one and the onyl beep code i got is one long loud continuous beep when only one of the 2 power supplies was switched on so that was just the PSU's telling me i had to turn the other one on. anyway, It's got a scsi controller with 3 scsi hard drives and one scsi cd-rom, i put in one IDE HDD and one IDE CD rom and nothing changed and it doesnt really do anything except power up fans and cd rom drives and the light on the scsi controller goes on, the fans on the processors are on but i cant really tell if its doing much else, no display on the screen just an orange light showing taht its sleeping...thanks for any help
