Gabriel,
We have several new IBM's, and have no problem with the BIOS using a
serial console. What are you attaching the box too? If you're using a
modem, how are you connecting to the modem? We have had some
configuration issues with a few modems, (I stronly recomend the USR
Courier V Everything for this), but never with a dumb terminal or a
portmaster.
Also, the IP KVM that gave everyone fits was a Belkin. That's been some
time ago. It was a new product line at the time, and would just freeze.
It would have to be power cycled. It also had a bad habit of confusing
the remote mouse and keyboard. Move the mouse, and garbage filled the
screen. Nothing you could do at that point but power cycle the unit. The
8 port Cyclades that took it's place has been working trouble free for
over 2 years now, and works with the Sun and AIX box that where
installed after I left, as well as the Intel based boxen.
The only way to idiot proof hard reboots is to keep idiots away from the
controls.
