peter 2001/10/31 22:19:32 PST Modified files: sys/boot/i386/boot2 boot1.s Log: Fix the ILLEGAL fdisk table that is there for supporting "dangerously dedicated" mode. This was specifying that there are 256 (illegal!) heads on the disk. If bioses store that in a byte, and it gets truncated to 0, then that almost certainly causes the infamous divide-by-zero nightmare. This is also most likely the reason why the Thinkpad T20/A20 series were locking up when FreeBSD was installed. This is also the most likely reason why a boot1 being present causes an IA64 box to lock up at boot. (removing the "part4" stuff from boot1.s fixes the IA64 boxes and would most likely have fixed the T20/A20 and some TP600E series thinkpads) Revision Changes Path 1.17 +2 -2 src/sys/boot/i386/boot2/boot1.s To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
