The next time, I made /boot sda2 and picked sda for the bootloader.
This time I got an install, but I'm not sure how to boot to it.
I'd rather not have to play with the BIOS
every time I want to boot a different install.
Is there a way to chainload to sda?
I'd have tried configfile,
but I don't think that works from old grub to grub2.
This is not quite clear to me. It sounds like you can now boot F16 or
whatever you had before by changing the BIOS boot drive. Is that where
we are?
GRUB Legacy can chainload the bootsector of the second drive with the
chainloader command.
chainloader (hd1)+1
Thanks.
Chainloading worked, Grub 2 didn't.
GRUB Loading stage1.5
GRUB loading please wait...
Error 18
Huh?
I thought that Grub 2 was supposed to be smarter than old decrepit Grub.
1023 cylinders or not, sda2 was my /boot from the first time I installed
fedoralinux to some considerable time after I put in the second drive.
Old decrepit Grub handled it.
Why not wave of the future Grub?
Also note that sda2 does not cross the 1023 cylinder boundary.

I'm pretty sure it is Grub 2.
Not only do I have a brand new grub2 directory with nearly 200 files in it,
