After upgrading from Red Hat Linux 6.0 to 6.1, the "dos"
label in lilo.conf would not boot if selected.  Upon
comparing the lilo.conf file placed in /etc by the upgrade
with a the lilo.conf on another machine which was similarly
configured, I pulled the following entries out and placed
them in the upgraded lilo.conf, re-ran /sbin/lilo and
corrected the problem:

other=/dev/hdb1         # existing entry
	label=dos       # existing entry
	table=/dev/hdb  # added
	map-drive=0x80  # added
	   to = 0x81    # added
	map-drive=0x81  # added
	   to = 0x80    # added

The problem with lilo.conf has occured on three machines
upgraded from RH6.0 to RH6.1.

Users upgrading from 6 to 6.1 may be frustrated if they need
to operate in a dual-boot system.

Yours truly,
Jon L.
