I was one of maybe 10 or so booting NetBSD on the Dreamcast too. This
is kinda similar in feel.

Maybe not so straightforward:

partition> P
8 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]

Label disk [n]? y
disklabel: ioctl DIOCWDINFO: Label magic number or checksum is wrong!

Label not written

I'll have to figure that one out. I did write zeros to the front of
the disk using dd, so it should have started clean. It's an 8 gig sdhc
card in a USB card reader. Seems like it should work, it shows up
pretty generically:

umass0 at uhub1 port 2 configuration 1 interface 0
umass0: SDMMC M121 USB 2.0  SD/MMC READER, rev 2.00/2.01, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <USB 2.0, SD/MMC Reader,
\001\000\000\001> disk removable
sd0: fabricating a geometry
sd0: 7790 MB, 7790 cyl, 64 head, 32 sec, 512 bytes/sect x 15954944 sectors
sd0: fabricating a geometry

(this is using the disk2 USB port on the NSLU2 by the way)

So the next question is if you can reboot it from NetBSD. If so, I
could have a script that does the ping, the telnet with the break, and
maybe get expect to handle doing the tftp boot.

Anyways. More fun awaits. Thanks again.
