>Number: 3124 >Category: i386 >Synopsis: BOOT_PROBE_KEYBOARD hangs system in bootblocks >Confidential: no >Severity: serious >Priority: high >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Thu Mar 27 11:00:04 PST 1997 >Last-Modified: >Originator: Nick Sayer >Organization: Just me >Release: FreeBSD 2.2-RELEASE i386 >Environment: Award BIOS, 486, no keyboard >Description: If you set BOOT_PROBE_KEYBOARD=true in /etc/make.conf and rebuild and install the resulting boot blocks, the system will hang on reboot. If you plug in a keyboard while it is hanging, it will instantly start booting as if a keyboard was plugged in. The probe is obviously hanging when no keyboard is present. Let me be clear.... It is hanging _after_ the boot blocks are loaded from disk. It is not actually hanging in the bios itself. I know this because I was testing with a VGA monitor hooked up and watching the disk light. >How-To-Repeat: >Fix: The workaround is BOOT_FORCE_COMCONSOLE, but that is less desirable, obviously. >Audit-Trail: >Unformatted:
