More information...
The number of heads that the "diskinfo" reports is different depending on
whether the compact flash card is plugged into the soekris box or mounted
in a USB card reader/writer.
The usb reader/writer reports:
da0
512 # sectorsize
2052513792 # mediasize in bytes (1.9G)
4008816 # mediasize in sectors
249 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
The soekris box reports:
ad1
512 # sectorsize
2052513792 # mediasize in bytes (1.9G)
4008816 # mediasize in sectors
3977 # Cylinders according to firmware.
16 # Heads according to firmware.
63 # Sectors according to firmware.
This is the same compact flash card.
I gave up on boot0cfg and booting from the second partition, so I took the
compact flash card out of the soekris box, connected it to my workstation
with a USB card reader, and wrote a whole new image to it.
Even after doing this, boot0cfg still won't work. I noticed some new
messages on the console when I tried "boot0cfg -v ad1":
ata0: FAILURE - non aligned DMA transfer attempted
ad1: setting up DMA failed
boot0cfg: read /dev/ad1: Input/output error
ad1 is attached to ata0, per dmesg:
ad1: 1957MB <LEXAR ATA FLASH CARD 20060911> at ata0-slave WDMA2
I think this means there is some kind of geometry problem here, but I
don't know how to fix it.
I'd like to find a solution to this, but it's not critical.
