Hi Experts,
I am trying to boot Linux from USB using coreboot and FILO and not able to find any documentation what parameter should I set on FILO prompt. I have enabled USB support while building FILO and libpayload.
Booting from hard disk works fine as below.
Start qemu with -hda disk.img option and give following on FILO prompt
<filo>root (hd0)
<filo>kernel /boot/vmlinuz-2.6.20 root=/dev/hda console=ttyS0
<filo>boot
Now I am trying to boot from USB and start qemu with
-usbdevice disk:disk.img
I am not finding any information what parameter should I set. I tried using root (hd0) (hd1) (sd0) FILO is not able to find my kernel image in /boot/
See errors below.
filo> root (hd1)
filo> kernel /boot/vmlinuz-2.6.20
Drive 1 does not exist
Error 15: File not found
filo> root (sd0)
filo> kernel /boot/vmlinuz-2.6.20 Unknown device type: sda
Error 15: File not found
filo> root (hd0)
filo> kernel /boot/vmlinuz-2.6.20
Drive 0 does not exist
Error 15: File not found
filo>
Can someone please let me know what is expected device name for the usb I enabled in qemu?
