We just "fixed" this sort of problem for ppc64 the other day. Course we don't use bzImages but rather zImages but none the less it was still anoying since we can boot zImages over the network and of course that makes it quite reasonable to blow past the 1.44 floppy limitation. The bug we fixed was that an uncompressed kernel could only be up to 4 meg in size, if it was larger, at uncompression time you'd just lose everything past the 4M mark. Todd Inglett raised the limit to 8 meg for us, and that's a mighty large penguin.... Regards, Tom -- Tom Gall - PPC64 Code Monkey "Where's the ka-boom?
