As the one who did the actual coding, I can confirm that the approach adopted in both the new bootblocks and the boot loader is virtually identical to that used in the older (biosboot) bootblocks. In all cases, the simplest approach giving the smallest code sizes was used, so there's very little difference between the three sets of routines. The above applies to 3.0-current. In 3.0-release, the boot loader was still using BIOS routines (with hardware handshaking), but this was changed around late November 1998. -- Robert Nordier To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
