Not understanding Grub
Registered Linux user #393103
When you say it assumes you want to install to the master drive, I believe those are just examples.
Or you might be referring to putting Grub on the MBR. This is a necessity, In order for Grub to be able to boot your OS, it needs to be on the MBR. Unless you want to put it on a floppy of course.
You are right that the first partition on the slave drive would be (hd1,0) or /dev/hdb1.
The kernel panic might be due to an error in your /etc/fstab.

If there is an error in your grub.conf it will also throw a kernel panic error. A mount point block (0,0) error is a error in the kernel line. Lately, the initrd line makes gentoo throw an kernel panic message/halt.

If you want to understand how Grub boots and what it "sees", I'd suggest making a Grub boot floppy and then trying different things. If you have Grub installed (not necessarily as the bootloader: you just need the Grub package on the system), you can read the instructions for creating a boot floppy if you do 'info grub' then choose 'Installation' and then find the section on installing to a floppy disk (press 'q' to quit from the 'info' command). I think the commands are these:Code:
/sbin/grub root (fd0) setup(fd0)
The cool thing is, you can poke around extensively without ever booting your system until you are ready. The Grub boot floppy can also be used to install Grub to the MBR "natively" and it serves as a useful rescue boot disk./IMHO
///this use to look better
Hmm.. ok thanks.
I just completed my Gentoo Stage 1 install last night so I threw Lilo on there, it's very easy to configure so I figured there would be no problem - there wasn't. I also was just finishing up on the install at about 1 am last night so I didn't really want to have to deal with a kernel panic on that first boot if I messed something up so I just did Lilo. I can later mask Grub over it if I really feel like it, just add the Grub package, install from the prompt "Grub>" thing and tell it to go to the mbr, etc. I'm just a bit confused because of all the examples are written for Gentoo to be installed to the master is all. I might make a Grub floppy and go from there.Registered Linux user #393103
