I still can't seem to get NanoBSD running on an ALIX board. I have tried everything mentioned in the list it seems. Maybe I am overlooking something? I even tried to go into sysinstall's fdisk and change the bootloader to standard mbr (no boot selector) for the da0 device (flash card) now i get the error: DISK SLICING WARNING: chunk 'da0s1' [63..997919] does not start on a track boundary any other suggestions? Could it be the fact that I am using the card on the USB interface and info isn't getting written to the proper geometry? (my ide card reader should be here tomorrow reguardless) On Dec 10, 2007 4:07 PM, Markus Dolze <bsdfan@nurfuerspam.de> wrote: > Markus Dolze wrote: > >> :/ I get what you are saying, but i'm not quite sure i understand how > to do > >> /:/ that.
