hi all,

I download the newest l4linux by using svn and use the x86-native_defconfig to configure the l4linux

then modify some place:

process and the keyboard,vga

 

then I can boot l4linux with the given drops-rd.rd through serial.

but when I use the same l4linux kernel to boot it on the national hardisk throug serial.

I came across the following problem:

 

Please append a correct "root=" boot option. Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

I have following someone's step as the google:

http://www.linuxquestions.org/questions/linux-kernel-70/kernel-panic-not-syncing-vfs-unable-to-mount-root-fs-on-unknown-block20-688150/

...

but the error still exist!

 

I do the things in vmware.

the menu.lst is:

title l4linux26+serial

#my hardisk is /dev/sda1

root (hd0,0)

module /boot/l4linux/l4linuxserial.cfg

module /boot/l4linux/loader --fprov=BMODFS l4linuxserial.cfg

 

the l4linuxserial.cfg is:

modpath "(hd0,0)/boot/L4Linux"
task "vmlinuz" "earlyprintk=yes console=ttyLv0 init=/bin/sh mem=256M l4ser.vkey_enable=1 root=/dev/sda1 ide_generic.probe_mask=0x3f"
all_sects_writable
allow_vga

 

thank you!
