Hi,
I'm obviously missing something here.
I'm trying to get nanobsd on a 512Mb flash card. The only changes
I've made are to set kernconf = net4801 in make.conf and to set the
Makefile disk geometry variables. "make" chokes on the disk geometry,
so I'm assuming I've set it wrong.
My diskinfo shows as:
mwl-crash2~;sudo diskinfo -v da0
da0
512 # sectorsize
512483840 # mediasize in bytes (489M)
1000945 # mediasize in sectors
488 # Cylinders according to firmware.
64 # Heads according to firmware.
32 # Sectors according to firmware.
I tried to put this into the nanobsd/Makefile as:
from Makefile:
# Physical disk paramters. Use diskinfo(8) on the target platform
# to find the correct numbers. We assume 512 bytes sectors.
HD?=64
SC?=32
SECTS?=1000945

Any thoughts?
