It's weird... it's clearly not random, but the pattern is shifting all over the place. Almost makes me want to guess some kind of bitmask (the 0xaaaaaa00 bit and the stretches of 00 and ff kind of hint that way) but even then it doesn't really seem to make a whole lot of sense. Perhaps it's a data segment of some code which is barfing on memory.
960 bytes at 0xc000 (48K)... almost makes one wonder if someone confused address 0xc000 with segment 0xc000 (the VGA BIOS)...
