>Description:
	After sysinstall for 4.9RC1-4.9RC4 (from posted ISOs), with our without installing BootMgr and/or setting the FreeBSD partition as active, F2 should boot FreeBSD but fails. Rather than loading the kernel from /, it immediately reboots.

	FWIW, sysinstall & BootMgr/BootEasy work properly from 4.5-RELEASE through 4.8-RELEASE & 4.8-20030801-snap.

	More history available on freebsd-stable@ under "FreeBSD 4.9 RC1 (i386) now available" & "Re: Final 4.9-RC (i386) available now, please help test.".
	
>How-To-Repeat:
	Install FreeBSD 4.9RC1-4 on HP Pavilion 7915 with NTFS (XP) on partition 1 & FreeBSD on partition 2.
