Second, this is ARTiGO with no serial and no PS/2 keyboard - only USB. There are certain times where FreeBSD lacks USB keyboard support. The MBR boot loader seems to leverage BIOS USB Keyboard support and works. Thereafter, boot block (override boot.config), loader (override loader.conf), the "beastie menue" (disable ACPI, safe mode, ...) and kernel debugger have BIOS USB keyboard dropped but do not support vanilla USB keyboard so I end up with not being able to type any key! Now realize how hard it was to get there :-| Cheers -- http://thomas.lotterer.netReceived on Mon Jun 15 2009 - 19:03:07 UTC
