Problem booting from compact flash (kernel panic)

I used this article to install linux on a compact flash...as per the article i have copied /boot/* to the flash(including vmlinuz and grub.conf)...i m using fedora 7 and my grub.conf looks like this :



# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,6)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
default=1
timeout=10
splashimage=(hd0,6)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.21-1.3194.fc7)
root (hd0,6)
kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.21-1.3194.fc7.img
title Windows XP
rootnoverify (hd0,0)
chainloader +1


Also,when booted i get GRUB command line as given in the article...i executed these commands..

GRUB> root (hd0,0)
GRUB> kernel /boot/vmlinuz root=/dev/hda1 rw init=/bin/sh
GRUB> boot

Following the boot command..vmlinuz opens and then a few steps later i encounter the following error:
cannot mount on root=/dev/hda1
append the correct "root="boot option
kernel panic:cannot mount vfs

Can someone correct me,where i m going wrong...is it required to modify the grub.conf file?Or should i give "root=" some other device?...is there any other website that gives detailed procedure to deploy linux on the compact flash?...help required urgently...Thank you in advance

You have installed on compact flash?
Might be you should device name /dev/disk or whatsoever is the name of flash drive on you linux, check in /dev directory.
GRUB> kernel /boot/vmlinuz root=/dev/disk rw init=/bin/sh
instead of
GRUB> kernel /boot/vmlinuz root=/dev/hda1 rw init=/bin/sh

I tried it and it didnt work....If u see, i have used Julian Coccia | blog procedure, wherein i have created only four devices(hda,hdb,hdc,hdd) under dev of the compact flash...so there is no disk directory as in the case of /dev of fedora7...shud i create more devices to boot correctly from cf??

I tried the same procedure and 'm getting the same results.
Kernel Panic
But another screen message is maximum stack depth used 5126 bytes remaining.
My flash drive is 1 GB only i do think the kernel we have used occupies greater space than what we have in flash.
I used 2.6.24.
