I pretty much have to guess and remember. I have no way of knowing if a command was successful. Maybe you have the chance to prepare access with a serial terminal (real one or per terminal emulator)? oh, and the third problem is that this new one uses a USB keyboard and I only have a PS2 keyboard. The kernel will detect it and attach it to the ukbd driver, together with the kbdmuxer you should be able to just use it, even if an AT style PS/2 keyboard interface is present on the system (but without the possibility to connect a keyboard). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Maybe you can check this in the old setting? As for the screen I've usually done without, I know my system well, but 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. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Additionally do a swapoff and use glabel label to label any swap partitions. Don't forget to update fstab before doing a swapon or rebooting or you might overwrite the label. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
