>Description:
Module digi.ko can't initialize Digiboard PC/Xem ISA multiport
serial card on old Pentium-100MHz machine.
Error message during boot or manual module loading:
digi0: BIOS boot failed (0x00 != 0x4447)
>How-To-Repeat:
1. Apply following patch to enable verbose init process:

2. Place these lines in /etc/make.conf:

CFLAGS+= -DDEBUG
.endif
3. Recompile digi.ko module and load it:

# make cleandir && make obj && make depend && make
# cp digi/digi.ko /boot/kernel

>Fix:
Period given to digiboard bios to run is too small. In current version of
sys/dev/digi/digi.c it is 2 * hz ticks, actually it takes my card a little
longer to initialize (logged with default hz=100 value):
