You do select an IRQ and base address DMA, etc. for each or are already set for you. > So i tryed with linux (i was very interested in that os at the time) and I > noticed that on the boot procedure it had to reset the drive (actually the > probing process stopped on that drive and lost about 30 sec to find a way to > communicate with it). I never ran across that for Linux, but sence I have never used IDE CDROMs or and other IDE device other than a single HD on my own computer. The only thing along these lines is I did have to set the time for SCSI recognition a little higher for my SCSI tape drive to be recognized. I also had to do this in DOS. > I don't know if it is similar to Utz Zarwell problem, > but i > think that problems with 2 cdroms of different manifacture are > very common.

What you probably ran into there was an OEM board made for ASUS and ASUS themselves probably could not write a driver for that chipset. The company that buys these OEM boards often have their own BIOS and they are also responsible for writing drivers for OEM products. I ran into this mess with Gateway with those OEM boards.Even brand name boards made for these companies like Gateway, they have to provide their own drivers. > There are only 3 MainBoard (and 3 video chipset designers...) brands chipset > that support AGP, and none of them products is fully compatible with the > standard!

I wanted updated drivers for it. I went to the NCR site and found they no longer make these chips and the whole ball of wax was bought by Symbios. I went to their site and got the latest software and drivers. They did not work very well. So after doing some research, I found that Tyan actually manufactured the board. I went to Tyan's site and downloaded their latest software and drivers. Those drivers work just fine. > Should we talk about the i740 bug? > > "This Hard Disk uses the zzz yyy standard, BUT we recommend to not use it > with yyy zzz products.
