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 enable the sata disk support!

...

I have following someone's step as the google:

http://www.linuxquestions.org/questions/linux-kernel-70/kernel-panic-not-syn... ... 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) kernel /boot/l4linux/bootstrap -serial -modaddr 0x02000000 module /boot/l4linux/fiasco -nowait -nokdb -serial_esc \ -comspeed 115200 -comport 1 module /boot/l4linux/sigma0 module /boot/l4linux/roottask task modname "bmodfs" attached 4 modules module /boot/l4linux/names module /boot/l4linux/log module /boot/l4linux/dm_phys --isa=0x00800000 module /boot/l4linux/simple_ts -t 300 module /boot/l4linux/rtc module /boot/l4linux/l4io module /boot/l4linux/bmodfs module /boot/l4linux/libld-l4.s.so module /boot/l4linux/libloader.s.so module /boot/l4linux/vmlinuzserial module /boot/l4linux/l4linuxserial.cfg module /boot/l4linux/loader --fprov=BMODFS l4linuxserial.cfg

the l4linuxserial.cfg is:
