The screenshots were made with an up to date (at that point of course) 8-CURRENT. But I've tried to boot with the snapshot ISO, which boots fine. Summary: - the original problem: with a fresh pxeloader, the machine halts at this point: http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-6.png - 8-CURRENT, booting with an older pxeloader panics with this: http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-55.png - the 640kB patch panics with this (8-CURRENT, older pxeloader): http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-70.png - with safe mode, I get this (8-CURRENT, older pxeloader, apparently no NICs recognized): http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-78-safemode.png - the December snapshot ISO with CD-ROM redirection boots fine, and it seems the SMAP is OK too: http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-78-fbsd8-amd64-livefs.png According to these, I think my problem is the pxeloader's inability to boot on this machine. An older one can't boot because of the memory-related difference, a newer one can not boot because of another changes, happening in-between. Somebody please help. :) I don't know if there is a version, which can get to the loader prompt AND initialize what need to be initialized correctly to overcome the SMAP-panic.
