Hi,
when I try to boot my notebook from a USB disc, the system freezes
completely. After displaying the text (or menu), it doesn't react to any
key, even Ctrl+Alt+Del doesn't work. The config is pretty simple:
-------------------------------------------
SAY Booting Linux from USB...
KERNEL /boot/vmlinuz
DEFAULT Vaio
PROMPT 1
LABEL Black
KERNEL /boot/vmlinuz
APPEND ro initrd=/boot/initramfs console=ttyS0,38400 console=tty0
vga=0x307 HOST=Black
LABEL Vaio
KERNEL /boot/vmlinuz
APPEND ro initrd=/boot/initramfs console=ttyS0,38400 console=tty0
vga=0x305 HOST=Vaio
-------------------------------------------
With "PROMPT 0", it boots without problems.
As the same configuration works well with my PC, I guess it has
something to do with the BIOS. The notebook is a Vaio VGN-Z21VN, approx.
6 years old.
Any ideas?
Regards,
Bernd

And actually commenting it out didn't change anything.> When using "PROMPT 1", you should see the "boot:" prompt.Yes I see the prompt (as I did before).> Pressing [Enter], should boot the "Vaio" label.I know it _should_ boot, but it _doesn't_, that's the problem. At this point, the only thing I can do is a hard reset. Bernd -- http://sudrala.de

Also look for USB Legacy and keyboard options in the BIOS setup. -- Regards, Feri.
