AHCI/IDE configuration not found in BIOS==kernel panic sync
I'm running Red hat 4 on vmware workstation7.Initially the kernel was 2.6.9-5.I wanted to compile a new kernel,previously I've done so with Ubuntu8 and that was two years back-a debian distro.
I wanted to check out compiling rpm distro's.So I download 126.96.36.199 from the pub.I followed all the steps provided in HowToKernel configuration of digitalhermit website,build the initrd image properly & everything-put the following entry in my grub.conf
title Red Hat Enterprise Linux ES (188.8.131.52)
kernel /bzImage-184.108.40.206 ro root=/dev/VolGroup00/LogVol00 all-generic-ide pci=nommconf acpi=off rhgb quiet
title Red Hat Enterprise Linux ES (2.6.9-5.EL)
kernel /vmlinuz-2.6.9-5.EL ro root=/dev/VolGroup00/LogVol00 rhgb quiet
Now one thing did turn up,it said mptbase module cannot be found before I build the initrd image.So I removed the alias section containing mpt from /etc/modprobe.conf & initrd image compiled successfully.
I've checked my labels in fstabs,blkid & compared it to entry in grub.conf to check whether it is consistent or not.It was on the mark.
So now when I booted the kernel it gave the following error message
File descriptor 3 left open
No Volume group found
mount:error 6 mounting ext3
mount:error2 mounting none
umount /init/dev failed
kernel panic-not syncing
On looking around further I found out,I've to turn off ide mode in advanced peripherals of bios & set it to ahci.I could not find that option in vmware bio's.Bio's which vmware uses is Phoenix.
So what would be the possible remedy,do I've to upgrade vmware bio's(I could not find any comprehensible link on that). or is there any other thing I missed.
Thanks for your time & help.
