The card is a PCI card which I had to use to access a new hdd. The system bios would not access the drive. Yes, I can boot off of it. I have 2 hds attached to it. After I get the OS up, both drives are available. This was not the case when I first installed the card. I opened a trouble ticket with Fedora as Fedora would not recognize the slave drive - only the master. The card has an ITE IT8212 controller chip. I don't understand your questions about bios disk number or the play nice with the BIOS boot spec. How do I find the answers to these questions?

The Fedora Bugzilla bug number is 344231 in case you would like to read about my original problem.

Thank you for the quick response.

My understanding, as a user of GRUB, was that GRUB relied on the system BIOS to perform any disk I/O, thunk to RM to invoke INT 0x13 for all disk accesses.

Is the disk controller visible for the system BIOS? Can you boot off of it? Is there a bios disk number assigned to it? Does it play nice with the BIOS Boot Specification or does hook INT 19?

I am having a problem with GRUB 1 and 2. It seems that neither version correctly works with my IDE controller. I have 2 hdds but grub (both versions) only recognize the first. From what I can determine, I am unique in having this problem and the only way to get it fixed is to do it myself. So, here is my request - can someone point me to the module that would determine the type of IDE controller installed where I would have to insert some code to have the controller report the correct number of hdds attached? I have downloaded the source code for grub2.

Any guidance would be greatly appreciated.

Thank you,
Vince Radice
