Dual-boot W2K/Redhat
 
I am trying to setup dual-boot without floppy on following config:
IDE0 master (hda)- Redhat, IDE2,3(AMI MegaRaid 100) RAID0(stripe) - W2K. I can boot from RAID100 no problem, I also can install Redhat with MBR and boot of IDE0 or install LILO to hda1 header and boot into Redhat with floppy. I tried copying hda1 header to use Win2k dualboot, (dd if=/dev/hda1 bs=512 count=1 of=/mnt/floppy/linux.bin - add linux.bin path to boot.ini), but it would not work (selecting LINUX option leads to display "LI" and stop). Kernel 2.4 does not support AMI RAID controller on Iwill KA-266R, so it sees two drives in stripe as separate corrupte drives.
And it seems to me that this would prevent me from dual-booting with LILO. Did anyone try something like this and is there solution, if I don't want to install W2K on IDE0? Thanks!

Hurray
 
I got it to work, persistance finally paid off.
I followed dual boot mini-HOW-TO to a point, tried program "bootpart", still no-go.
So I followed http://www.linuxdoc.org/HOWTO/mini/Linux+NT-Loader.html
installed Redhat to IDE0 , the section that talks about copying first 512 bytes of hda1 didn't work for me, but for some reason the this one did:
"Run lilo with a diskette inserted. Now try to boot from the diskette. If your Linux on /dev/hdb1 can't be started, the NT OS loader will also fail to start it. If you see a lot of 01 01 01 01, your root-disk is not accessible. Check whether all your disks are known by the bios. If the floppy boots your Linux partition, you can peel of your boot-sector for the NT OS loader with:

# dd if=/dev/fd0 of=/bootsect.lnx bs=512 count=1

You can keep this diskette as your rescue-diskette just in case your Windows NT installation breaks.

I hope this will help somebody else:)
