Boot PC from Compact Flash

[manisha s]

Hi All,
I m new to this mailing list.

I want to boot my laptop from 128Mb Compact Flash(CF)
Card.
On laptop i have already RedHat 9 with kernel version
2.4.22.

I downloaded the pebble linux distribution and
successsfully downloaded (wrote) this on to the CF.

The CF card is available as /dev/sdb on the linux
through CF card reader/writer.

I changed /etc/grub.conf file so as to include the CF
card

title Pebble(Pebble)
        root (hd0,1)
        kernel /mnt/pebble/boot/vmlinuz-2.4.22-pebble 
ro root=/dev/sdb1

title Red Hat Linux (2.4.22)
        root (hd0,1)
        kernel /boot/vmlinuz-2.4.22  ro root=/dev/hda2
        initrd /boot/initrd-2.4.22.img

should i copy the vmlinuz-2.4.22-pebble to /boot
directory?
should i change other than this?

plz shed some light on this issue?

Thanks in advance

This has little to do with LinuxBIOS I'm afraid.

Your CF reader probably connects via USB and the usb-storage layer
in Linux presents it as a SCSI device.

GRUB does not include a USB stack. It can not load the kernel from CF.

If you really want to boot from the CF, get a 2.5" IDE-CF adapter,
search this mailing list archive for URL.

If you want to know whether LinuxBIOS could run on your laptop, which
unfortunately is unlikely due to the high degree of customization
common in laptop mainboards, you should send us lspci -v output.
