Maybe you can check this in the "old setting"? > As for the screen I've usually done without, I know my system well, but=20 > if the disk moves, I'm lost. For the keyboard, maybe a PS2 to USB adapter? If you have a USB keyboard, you can directly use that - after the kernel has come up, the keyboard can be used. PRIOR to that point, it may needed to enable some kind of "USB keyboard legacy support" in the BIOS / CMOS setup. I'm using a native USB keyboard here (Sun Type 7) which can't be used until the kernel loads ukbd; for emergency purposes, I still have to attach a regular PS/2 keyboard to the powerless system... or use the HIL plug to plug the keyboard cord into the keyboard - yes, it's an IBM model M. :-) An adapter from PS/2 to USB (if you don't have a USB, but a PS/2 keyboard) should also work. I have a cheap one (from China) here, works very good. But as I mentioned, it's also possible to make FreeBSD booting to and accessing from a serial console, no matter if you use a real serial terminal (e. g. DEC vt100), a laptop with a serial cable and a terminal program (e. g. cu), or a means to connect to the serial port that provides telnet access (such devices are often found in datacenters, and some of them allow accessing a system's serial console through a web interface). In the past, I had some headless Sun boxes (Sparcs and Ultras) that I connected to using a real serial terminal - fully sufficient, used less than once per year. :-) --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
