But this may not solve the problem. If your BIOS does not know how to access the drives on the Silicon Graphics card, and you chainload the copy of Grub on the MBR of hde, that first stage tries to use the BIOS to load the second stage. The reason the floppy boot works is that both the first and second stages are on the floppy, so Grub can use its own code to access the drive.
