I tried 'boot0cfg -o packet /dev/da0' but with no luck. With that setting i tried CHS and LBA mode on the alix board, both with the same result. So i guess this is the GEOMETRY problem you were talking about (and have since read quite a few pages about). I'm afraid i don't exactly understand the part about "You'll need to set this geometry on the flash by having the partition end exactly on a cylinder boundary so that the BIOS and FreeBSD will be in sync as to the geometry of the device." I get what you are saying, but i'm not quite sure i understand how to do that. I specified the info from diskinfo -v /dev/da0 and put it in a myconf.conf file for NanoBSD... i thought that would take care of it. hostname# diskinfo -v /dev/da0 /dev/da0 512 # sectorsize 512483328 # mediasize in bytes (489M) 1000944 # mediasize in sectors 488 # Cylinders according to firmware. 64 # Heads according to firmware. 32 # Sectors according to firmware. hehe sorry never had to deal with such a lowlevel problem! i'm learning.. i guess i can go pick up a pccard adapter of some sort. I am trying to keep this off my laptop, so would a PCI flash card reader work properly with writing the proper geometry? -- Lyle Scott, III http://www.lylescott.ws
