Has anyone done a dual boot like this?

I've got Redhat 9 and WinXP installed on my computer at the moment. I've got an Asus P4C800-E Deluxe board with an 80Gb IDE drive connected as primary master and two 80Gb sata drives connected in raid0 fashion. All 3 drives are connected to the ICH5R controller. WinXP is installed on the raid array and working fine. Redhat is installed on the IDE drive with grub written to the first sector of a /boot partition. That works fine too. The problem is with the actual dual booting. With my boot device set to be the raid array, I have tried to load grub from ntldr following some guides on the net. Basically I made a copy of the boot sector from my /boot partition and copied it over to Windows and edited by boot.ini. Most guides were basically giving the same instructions so I'm assuming this procedure is correct, but perhaps only for setups without RAID.

When I select Redhat at the boot menu, the word GRUB appears on the screen and it hangs. Does anyone know why that might happen? Is it because of the sata raid / IDE combination I've got? I've read many threads on different forums about dual boots but very few of them refer to a setup similar to mine. I can still boot into each OS but it requires either changing settings in BIOS or using a Redhat boot floppy. I'd like to know if there is a better solution to this problem before I resort to those. Any help is appreciated.

Redhat cannot read my sata raid array at all but Windows can read the FAT32 partitions on my Redhat drive. I have also tried to install Mandrake 10 on the same setup. It could see my two sata drives and even showed /mnt/windows/
but after installation I found that it totally messed up my raid array. So I guess that means stay away from Mandrake for now.

Mandrake reads the sata raid array as just 2 separate scsi drives at installation. It showed that on the first drive there was /mnt/windows and the second drive was empty. I'm not sure as to why it totally messed up my raid array with WinXP on it. Is it because of LILO, because that's what I chose as the bootloader at the time. I have read on some forums that LILO and WINXP don't go well together. I don't know I'm really new at this.

I'm only guessing... Maybe booting works if you delete the GRUB boot loader. If you choose Linux from XP boot loader, GRUB will then be the next bootloader to execute. If GRUB was removed then you should boot straight in to Linux without problems?
