- Note 2: The geometry of the cf card is defined in the nanobsd configuration file $R/cfg/nanobsd.wleiden
- The 'default' values are for a Peak 1 GB card. They also work on an Alix2D3 board with a 1 GB PCEngines 'blanc' cf card and 1 or 2 GB Transcend cf cards although those geometries are different. There are issues with Soekris boards, depending on the BIOS version. The geometry of the cf-disk is as follows:

-parameters extracted from in-core disklabel are: cylinders=1966 heads=16 sectors/track=63 (1008 blks/cyl)
-Figures below won't work with BIOS for partitions not in cyl 1
-parameters to be used for BIOS calculations are: cylinders=1966 heads=16 sectors/track=63 (1008 blks/cyl)
-Media sector size is 512
-Warning: BIOS sector numbering starts with sector 1
-Information from DOS bootblock is:
-The data for partition 1 is: 
-    sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
-    start 63, size 820449 (400 Meg), flag 80 (active)
-    beg: cyl 0/ head 1/ sector 1;
-    end: cyl 406/ head 31/ sector 63
-The data for partition 2 is:
-    sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
-    start 820575, size 820449 (400 Meg), flag 0
