Setup before the card that works: Asus A7V Mobo with BIOS revision 1009 60Gig Deathstar (master) -> 30Gig Deathstar (slave) -> Onboard ATA 100 4x4x24x Mitsumi -> Onboard ATA 100 8x Panasonic DVD (master) -> 50x Aopen (slave) -> traditional onboard IDE slot now everything works beautifully here with this setup Now the problems: I have this used Data Tech PCI IDE Controller card. When I put it in the computer won't boot. Here is more detailed information: 4x4x24 Mitsumi -> Onboard ATA 100 60Gig Deathstar (master) -> 30Gig Deathstar (slave) -> Onboard ATA 100 Now I go into my BIOS -> Advanced (Tab) -> CHIP Config -> Onboard PCI IDE Enable (this is different from my ATA 100 right?) -> it is set to Both (I did not change this originally). Then I go to my Boot (Tab) in the BIOS and here is the sequence: Floppy Other boot device: Onboard ATA 100 BOOT IDE Hard Drive: Disabled (Only options are disabled and none) ATAPI CD-ROM: None (Only options are disabled and none) Results: Memory check (fine) Detecting Primary Master: None Detecting Primary Slave: None Detecting Secondary Master: None Detecting Secondary Slave: None Then the screen where it shows the IRQ stuff I believe Next it Detects my 2 ATA100 drives (60 and 30gig) Next the boot menu screen (redhat and XP): I choose XP Never leaves this screen - whatever the 30 second timer was on when I hit enter is what it stays on - the system appears to be stuck at this state. What I have tried with the same exact results: Going into the BIOS -> Advanced (Tab) -> CHIP Config -> Onboard PCI IDE Enable -> it is set to Primary Going into the BIOS -> Advanced (Tab) -> CHIP Config -> Onboard PCI IDE Enable -> it is set to Secondary Going into the BIOS -> Advanced (Tab) -> CHIP Config -> Onboard PCI IDE Enable -> it is set to Disabled Now occationaly when its detecting primary master or secondary master it will freeze when it says press F4 to skip, but that doesn't happen often (2 out of the 8 times I tried and I dont' remember the exact BIOS settings I had when it did it). Now this card did "work" in my parents HP Pavilion 8275. I bought it when I was at home to put in their computer and I did and it would boot, was detected by WinME but the cd drive that was hooked up to it acted like the power wasn't on, I might have had the ribbon cable plugged in the wrong way..?.. Anyway maybe I'm wrong here but I thought if another system would boot with it in than mine should. Now when I remove the card it boots up fine. Anyone see any apparent reasons for the problem I'm having? One thing I have noticed: My Mitsumi Burner is NOT detected at any point when the controller card is in.
