nanobsd disk info

[Michael W. Lucas]

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

_.md.tmp reports:

Any thoughts?
