>Release:        FreeBSD 2.1 CD-ROM distribution
>Environment:

133MHz Pentium Intel Endeavour board
ATI Mach 64, Graphics Pro Turbo graphics card (PCI)

>Description:

When booting boot.flp (or atapi.flp) the boot reaches the point at which
the serial ports are probed, then the screen goes blank and the system
hangs.  The same happens if I run install from DOS.
The serial ports are configured the standard way.

>How-To-Repeat:

Boot the system from the boot floppy.

>Fix:
	
If I boot /kernel -c and disable sio0-3 the boot progresses to the
installation program.  I can then proceed further, but of course have
no serial ports.
(Since the CD-ROM drive (Stingray 8X IDE) is not supported and DOS
screws the dist files up if I copy them to a DOS partition I can't
install anyway, but that's the next problem).
I tried a Slackware Linux boot floppy, and that booted OK.
