I see. If you dig into your problem and give me some hints
why or where GRUB freezes, I would try to fix it.
Unfortunately, I myself have no BIOS which has such a feature.
Thanks,

=================== BUG #1184: FULL BUG SNAPSHOT ===================
Submitted by: hno Project: GNU GRUB
Submitted on: 2002-Sep-11 16:30
Category: Terminal Severity: Ordinary
Priority: Normal Bug Group: Software Error
Resolution: Works for me Assigned to: okuji
Status: Open Release: CVS
Reproducibility: Every Time Planned Release:
Summary: serial command freezes grub if serial redirection of BIOS is enabled
Original Submission: On certain boxes the serial command freezes grub. This is
seen primarily on Intel motherboards with serial redirection of the BIOS screen
enabled.
Might be related to a prior report on the grub-bug mailinglist from June
http://mail.gnu.org/pipermail/bug-grub/2002-June/007583.html
Hints on how to proceed in diagnosing what the error may be would be preciated.

Because the serial redirection of these boards is crap, only useful for getting
access to the BIOS in emergencies. Having native serial is highly preferable.
The BIOS redirection does some kind of screen scraping to detect screen updates
and often misses stuff.
The BIOS is somehow supposed to detect when the application uses the serial.
Should perhaps note that the serial support of LILO seems to work just fine
even with BIOS console redirection enabled, and so does DOS. To my knowledge it
is only GRUB who crashes..
Note: The serverity is of this bug is only minor. But until it is fixed it
might be good to know that there is such issues and is why I registered the bug
report.

As GRUB modifies the status of a serial controller when
initializing it, I think anything wrong could happen.
BTW, I'm wondering why you want to enable GRUB's own
serial support, if your BIOS supports serial console
transparently.
Thanks,
Okuji
