still cant find root

i have an ASUS 27V266 MB w/ via 266 chipset running an Athlon XP. It has dual ata-100 controllers. Now, when i try to boot up it tells me something like "vfs: cant find ROOT fs" and to make sure the "root" line in grub is passed correctly (which it is)

I've never compiled a kernel for an Athlon system before and can only guess something is wrong in kernel config. Interestingly, about a hundred google searches don't tell me exactly what ide controller is on that mb, but im only guessing that that is the problem.

We need more details... Your menu.lst, the output of fdisk -l /dev/hdX, etc...

ive looked at is so many times i know it by heart

dev/hda1----> primary, windows (at end of drive ~ 7gigs)
dev/hda2----> primary, linux boot (at beginning of drive ~ 100 megs)
dev/hda3-> extended partition for swap and root:
dev/hda5----> linux swap ~ 1500 megs
dev/hda6----> linux / ~18 gigs

here is menu.lst

Try this in menu.lst:

that didnt work... perhaps this will help...

here is more of what it says:
VFS: Cannot open device "hda6" or 03:06
please append a correct "root=" boot option
kernel panic: VFS: Unable to mount root ds on 03:06

it may, at times, sound like i know what im talking about, but i've never compiled a kernel for this system before so chances are i forgot something obvious in kernel config

You may have not included support for your hard disk controller in the kernel. This thread might help you find out what it is: https://forums.gentoo.org/viewtopic.php?t=5303.

those commands do seem helpful but running any of them doesnt tell me anything new or surprising
One entry from cat /proc/ioports is VIA Technologies, Inc. Bus Master IDE, and VIA is built in under ATA/IDE/MRM support in kernel config.

Here is some more info from kernel config. Keep in mind im using an Athlon XP, Asus MB A7V266, with aVIA Chipset:

Processor type and features: Low Latency, Control LL w/ sysctl, Athlon/Duron/K7 proc. fam., Machine Check Exception, Model Spes. Reg. Support, Cpu Info support, Preemptible Kernel (all built in). (CPU scaling causes make to fail so i dont think i need it)

General setup: Networking, PCI Support (any access mode), PCI device name database, Sys. V IPC, Sysctl suport, ELF kernel and binaries (all built in)

skipping down to ATA/IDE/MFM/RLL (built in). And under block devices submenus:
Enhanced IDE/MFM/RLL disk/cd/floppy support, IDE taskfile access and IO, Generic PCI IDE chipset support, Sharing PCI bus-master DMA support, Use PCI DMA by default, VIA82CXXX chipset support (all built in)
As modules in the same submenus....
Include IDE/ATA-2 Disk support, cdrom support and floppy support. I found them as modules so thats how i left'em. I think ATA/IDE/MFM/RLL was originally a module so when it first didnt work i made it built in. I'll try module again now.

Under filesystem i made sure ext3 was built in. Kernel compliation always finishes with a message about "noting to be done for modules_install" is that normal.

please delete the post i accidentally placed as its own thread. I posted as guest from another comp. and didnt realize what i'd done till it was too late. :oops:

actually it sats "no rule to make targe 'modules_install' but i doubt that helps

when i boot off the cd, right where it crashes on the hd it says RAMDISK: compressed image found at block 0. could this have something to do with it?

Is your drive connected to the Promise controller?

i solved this problem and forgot to mention it. i deleted my kernel's config file and started from scratch and compiled the latter but not the former into my kernel... when you boot does it say assuming 33mhz bus override with idebus=xx? my performeance doesnt seem to suffer but its unnerving nonetheless. maybe ill compile in promise next time i screw with kernel.
