2000-05-28 OKUJI Yoshinori <okuji@gnu.org>
* stage2/asm.S (codestart): Fix a typo: DISKLESS_SUPPORT ->
SUPPORT_DISKLESS.
* stage2/nbloader.S: Fix the image length and the memory length
fields. They shouldn't contain the first sector for a tag.
Mmh..., that is unclear as far as I see the Net Boot Image
Proposal...
* stage2/shared.h (STACKOFF): Enclosed with parentheses.
(PROTSTACKINIT): Likewise.
