You can find here a good howto regarding GRUB:

http://www.linuxquestions.org/questions/showthread.php?s=&threadid=237511

Also I suggest reading http://tldp.org/HOWTO/Linux+Win9x
+Grub-HOWTO/proc.html#AEN72 (tldp GRUB Howto) as you can find there
important informations regarding multidisk mapping (which seems to be
missing from your setup).


And as a 0.02$ thought: I don't think you would need a FAT32 512M
partition for bootloader.


HTH,
