Pko and Digiboy,

Thankyou for your replies. You're info is very helpful. The EMU tech wouldn't really help me out because they didn't want to be liable for any negative changes to Windows or the Adaptec controller. All they said was the E4x has an older "dumb" scsi in it. And the hang might be from the sampler never ansering a question from the scsi card, and the card sits and waits for the answer. Hmm, ok emu.

Pko, I'm using Win98 SE. My Asus Motherboard has U2 SCSI built in with the SCSI-Select bios. Yes there is an option to disable the bios on boot up. For termination it's like this so far. The Onboard SCSI has 2 separate busses. One for U2 (My barracuda drive) and another for SE/Fast Scsi devices (My DVD-Rom and CD-burner.) I have an IDE drive for my boot drive.

Right now the CD/DVD players are on the SE/fast bus. Separate from the U2 bus. The DVD is at the end of the chain internally, so it's terminated. The Scsi adapter auto terminates itself. If I tap off the ribbon cable going to my CD/DVD drives and out to my sampler, I've been turning on termination in my sampler. In effect my chain is then a in a Y config. So the DVD and sampler should both be terminated, right?

I also took the CD/dvd drives off the chain for troubleshooting and went only to my sampler. But couldn't get it to work. Exact same behavior, so I guess it's not a result of having my Cd/dvd drive on the chain at the same time.

I can't have my sampler upgrade to EOS 4.x without a flash memory upgrade. It really burns me that I bought this E4xTurbo 1 month before the Ultra series came out. I paid good money for the thing. I had no idea Ultra was coming and my supposed (friend) at the music store said nothing like that was coming down the line soon (cause I asked- and of course would've waited). So there it is one month later with Ultra's out at nearly 1/2 price. I was pissed. Sure, lets spend another $1000 so emu can change the motherboard and cpu that I just paid $xxxx for. Ack!

I'm drifting here. If I disable the SCSI bios, will that negatively affect any of my drives? or performance? I've hung the comptuer so many time last week, I'll go give it a shot and see what happens.

Thanks for replying.
