Hi, A while ago I added support for ATA support. It wasn't complete yet, but I rather have this in CVS than rotting on my harddisk. Besides that, it isn't *that* bad. I will describe the outstanding issues below.
First of all, this is mainly for i386-linuxbios. On i386-pc we have to disable biosdisk support because ata.mod and biosdisk.mod do not like eachother :-). Perhaps disk access via the BIOS will not be possible/safe anymore after loading ata.mod. PCI devices are not supported *yet*. Same for controllers 3 and 4. I will work on this. The code to detect the type of controller (PATA, SATA, PATAPI, SATAPI) really sucks. I will have a look at this. There is no code to detect the amount of sectors for a CDROM. I will write this eventually. Patches are more than welcome! The biggest problem is that grub_get_rtc is used to measure how long we have to wait for the hardware to settle. This function return the amount of ticks (1/18th of a second), this resolution is not acceptable. It will result in large delays in ata.mod because it will wait at least 1/18th of a second on i386-pc. For i386-linuxbios we still need grub_get_rtc.
