No, I'm multi booting my thinkpad, none of the operating systems which support the grub payload, this means I'm pretty much dependent on SeaBIOS + VGABIOS blob. That's ok for me. x86 openfirmware boot loader support on the other hand would be pretty cool ;) Sevan / Venture37 ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Hi Piotr, Unfortunately its not possible to boot freebsd with the libreboot images due to libreboot not have a binary blob vga bios seabios payload. You should be able to run freebsd without issue using coreboot however (libreboot is a consumer of coreboot which produces images without any close components). I've managed to reflash a stock x60s with coreboot run net/free dragonflybsd on there. I don't believer the laptops are modified physically in anyway just have their bios reflashed, might be worth asking them if you can get a laptop with coreboot+vgabios+seabios. Alternatively, just get a thinkpad x200 diy. You may have to resort to using linux for the initial flash. If it goes wrong provided you made backup images before starting, you can recover without issue using a raspberry pi or a beaglebone black as your reprogrammer the flashrom utility.

Re: Libreboot X200 and FreeBSD
So, the loader needs updating to have VGA framebuffer support. I have started that as an investigation but I don't have anything tidy enough to start pushing into -HEAD. But yes, as long as they expose the VGA framebuffer in some meaningful way (read: either they pre-initialise a dumb framebuffer, or they provide basic BIOS services for it) then it'll eventually happen. -adrian ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
Libreboot X200 and FreeBSD
I want to buy a Libreboot X200 notebook, however, I also want to use it with FreeBSD. I'm not sure if that works, so I asked Gluglug directly and got the following response: I'm given the impression that text-mode graphics initialization used to work on the X200, but was broken by a later commit. A bisect might help. phcoder-screen fchmmr: if it uses vbt or bios calls, it won't phcoder-screen fchmmr: first one should work, but FreeBSD works only in text mode Text-mode is currently broken on the X200. VBT or fake VBT is currently lacking in the coreboot port for X200 (VBT calls), and lacks INT 10H video services (BIOS calls). I'm not sure if FreeBSD will work correctly or not. It should work if you use the Video BIOS extracted from the original firmware (libreboot won't use or recommend this, because it's proprietary; instead, it uses a free but incomplete implementation called native graphics initialization). Can some FreeBSD developers make a statement on this topic? If it doesn't work, then I can test some patches, if someone writes them, but I'm a sysadmin, not a programmer, so I'm not really able to write some code. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
