Subject: [Patch] i386: build.c: Write out larger system size to bootsector
Date: Sun, 07 Aug 2005 20:12:59 -0600	[thread overview]
Message-ID: <42F6BFAB.4010807@tuxrocks.com> (raw)

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

This patch allows build.c to write out the full system size to the bootsector for system sizes larger than about 1 MB (1048560 bytes) by using another byte (a 4th byte would allow system sizes larger than 268 MB).
