[SOLVED] GRUB error after SATA port set as Native IDE

[ukagwx243]

Two years ago I installed Fedora 7 with Compatible SATA mode in BIOS because
the system didn't support DVD if set SATA mode in BIOS to Enhanced in Native IDE mode.

The version of kernel is 2.6.23.17-88, intsalled 4 sata hdds with 250GB/each.
Grub 0.97 is installed in the MBR of /dev/sda.
/etc/modprobe.conf:
alias scsi_hostadapter ata_piix
alias snd-card-0 snd-hda-intel

Now I will set SATA mode in BIOS to Enhanced(AHCI) /Native IDE mode
for install more sata hdds, but I will keep fedora 7 and will not upgrade this system because lots of program and libs.

I tested the system can not boot if set SATA mode in BIOS to Enhanced(AHCI) /Native IDE mode.

Is any way to fix this problem?
Thanks for help.

Hi and Welcome !

Which Motherboard/chipset do you have?

Thanks for the reply.
motherboard: Tyan S5382
chipset:Intel 5000P + ESB2

Like I said the problem caused by installation of Fedora 7, because the DVD drive
didn't work in Enhanced /Native IDE mode. I have to set Compatible SATA mode
to install fedora 7...

Do you get a grub menu up and does the kernel boot up to a point?? if yes then:

while booted in "Compatible SATA mode" rebuild the initrd (mkinitrd) and make sure the AHCI/SATA drivers are included (can't remember the command line option). The original initrd will not have the SATA/AHCI drivers in it.

A few workarounds are here. You have to compile kernel with proper support for your chipset.

Thank you all. I have already solved this problem through updating the system from network, not using DVD drive. Thanks again.
