Hold down the 'S' button while powering the system on. You will eventually be presented with a menu. Use the 'S' button or the up/down or left/right buttons to navigate the menu. Use the 'E' button to select options or sub-menus.
What boot and root options do I have?
That depends on your flash ROM version. The flash ROM stores the desired boot device in CMOS, but may not use it, depending on the boot option selected.
The 2.3.x flash ROMs can boot from:
- Disk: the kernel image is read from the boot device's / or /boot. The boot device is also the root device.
- ROM: the kernel image is read from flash ROM, but mounts the boot device as the root filesystem.
- Net: the kernel image is read from flash ROM, but mounts an NFS share as the root filesystem.
The 2.9.x and 2.10.x flash ROMs can boot from:
- Disk, ROM, and Net, as in 2.3.x
- Net/Net: the kernel image is read from an NFS share, which is also mounted as the root filesystem.
- Settings: the kernel is read from the specified kernel source. The specified filesystem source is mounted as the root filesystem. For example, it is possible to load a kernel from disk, but mount an NFS share as the root filesystem.
How do I change the boot/root device?
Either use the 'cmos' tool or the LCD boot menu. To use the 'cmos' tool:
# cmos -c bootdev [hda1|md1]
To use the LCD boot menu, navigate to the "Config boot disk" option, then select the device you want. If the device you want is not listed, you will have to use the serial console ROM interface, or the 'cmos' tool.
How do I change the default boot method?
Either use the 'cmos' tool or the LCD boot menu. To use the 'cmos' tool:
- cmos -c defboot [d|r|n]
To use the LCD boot menu, navigate to the "Configure boot" option, then select the method you want.
Can I use ext3 on my Cobalt?
Yes, but you need flash ROMs from the 2.10.x series.
