What Raid level are you using? You can only boot a software raid 1 array.

What do the first KB of the filesystem show?

dd if=/dev/hdeX of=bootblock.bin bs=512 count=4

The Promise controller is a pseudo raid controller. eg. the driver has the 
actual raid 1 and 0 logic and not the card. You could even convert the 
standard Ultra ATA 66 controller to a Fastrak 66 by soldering a resistor to 
the back. It works, I've tried it.

You did actually partition the disk did you?
I'm assuming that you are trying to boot from the root disk which would be 
a raid 1.

fdisk /dev/hde
create new partition
type fd
write

repeat for /dev/hdg

Create a raid 1 set of these 2 disks.

Create a filesystem on the corresponding md device.

When installing lilo it should print out 2 lines where it installs itself 
on both disks in the superblock.

I personally find this howto useful with respect to this.

Good Luck.
