I posted a message yesterday about a boot problem, this is just an update to that.

When I try to boot Gentoo I get the following message:

"VFS: cannot open device "sda4" or unknown-block(8,4)
please append a correct "root=" boot option
Kernel panic -not syncing: VFS: Unable to mount root fs on unknown-block(8,4)

<0> rebooting in 180 seconds.."

Is this a problem with yaboot.conf or because it is a kernel panic do I have to recompile?

On the advice of a Gentoo user of 2 years, my yaboot.conf now looks like this:

boot=/dev/sda2
device=hd:
partition=4
root=/dev/sda4
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
image=/boot/kernel-2.6.11-gentoo-r2
    label=Linux
    read-only
    sysimage=/boot/System.map-2.6.11
    macosx=/dev/sda5
    enablecdboot
    enableofboot

However, this is largely unchanged from what I posted inline yesterday.  Any help would be appreciated.  I have already recompiled my kernel, but I didn't know what changes to make.  It compiles okay I think.  The only change I made was to add Kaui and something else.  Really I get lost in the kernel options as they're not very verbose.  I don't intend to tinker with it in future.  This is probably where my problem is.  I followed the Gentoo handbook in setting it up, and a Dutch webpage.  I had to disable ADB support due to compile problems.

Thanks in advance,

Jon Lee
