The splash screen does not have to be on the same partition as the
kernel, much less the same drive. But it does have to be on a drive
the BIOS can access. (Grub uses the BIOS to access the drives.) If I
am reading thing right, it also has to be on the same file-system
type as the kernel images are. (Each 1.5 stage only understands one
file system type.) I do not think that Grub hard-codes the splash
screen graphics location. Because there isn't a NTFS stage 1.5, I
don't think you can put the files on a NFTS.
