Subject: kexec to launch second kernel
I found your email id from kexec site. I am using kexec to start a second kernel (grub4dos and then windows). I have installed Fedora Core 13 first and Windows XP later on disk. I am using kexec-tools-2.0.1.tar.bz2 and I just extracted it and ran ./configure and make commands.
I am using following commands to launch a second kernel -
Kexec -l /sbin/grub.exe
First I tried grub4dos 0.4.4 but did not work then tried grub4dos 0.4.2 but that too isn't working. I have copied grub.exe to /sbin. Also, copied menu.lst on windows partition. I am facing following problems with them -
Stuck at Launching GRUB when I use grub4dos 0.4.4 - It just stuck at Launching GRUB screen.
Keyboard not working when I use grub4dos 0.4.2 - With 0.4.2 version, grub4dos starts, shows some entries on screen then says failure. Then it tries to find /menu.lst but it doesn't (I don't know why as I have copied menu.lst in Windows partition (hd0,1). Then it neither finds menu.lst at /boot/grub/ or /grub. So it gives grub4dos command prompt but I can't enter any thing as keyboard is not at all responding. Even Caps Lock, Num Lock LED not blinking.
In both cases, I also tried using -command-line option in kexec -l /sbin/grub.exe and given -config-file but did not work.
Color black/cyan yellow/cyan
Title Start Windows
Sequence is - Fron GNU GRUB start FC13 à Run kexec commands from terminal à Should start grub.exe (grub4dos) à grub4dos should find menu.lst and launch Windows XP.
Please note that I can boot Windows XP from GNU GRUB with same menu.lst as above and also when I launch grub4dos as kernel from GNU GRUB and then grub4dos finds menu.lst and start Windows XP. I can't launch Windows XP using kexec.
Please let me know whether I am following correct steps and using right versions or not and a possible solution for this problem.
