Re: [Etherboot-developers] Building a ROM

[Ken Y. <ke...@nl...>]

|The problem will be one of:
|- Your code patches are being interpreted as the "third byte" of the option
|ROM, and are the source of the 1KB size.  Make sure that the first three
|bytes of the binary code you are feeding to makeROM are "0x55, 0xAA, <size
|in 512 byte blocks>" (from "loader.S").
|- You fed a small piece of "test" code to makerom to check it's operation,
|and although the first three bytes are correct, the overall size of this
|code _is_ 1KB.

Or he was using a buggy version of as86 and the starting bytes are not
55 AA at all. I have added a check for this to makerom.c so that it will
give the appropriate message in this case.
