hi,
I have a this SBC that boots off a CF card,
when it boots, I can select the boot partition via F1 or F2
and all is OK.
when I do it via boot0cfg the 'default_selection' changes
correctly, but the 'active' partition is not changed, so boot
ignores it.
I went ahead and changed boot0cfg.c to set the active
partition and now I'm baffled:
alix-3# ./boot0cfg -v ad0
# flag start chs type end chs offset size
1 0x00 0: 1: 1 0xa5 519: 15:63 63 524097
2 0x80 520: 0: 1 0xa5 1023: 15:63 524160 524160 ------+
3 0x00 1023:255:63 0xa5 1023: 15:63 1048320 2951424 |
|
version=2.0 drive=0x80 mask=0xf ticks=182 bell=# (0x23) |
options=packet,update,nosetdrv |
volume serial ID 0000-800f |
default_selection=F2 (Slice 2) <--------------------------------------------+
so far so good.
alix-3# ./boot0cfg -v -s1 ad0
...
1 0x80 0: 1: 1 0xa5 519: 15:63 63 524097
...
default_selection=F1 (Slice 1)
ok right? but no!
./boot0cfg -v ad0
...
2 0x80 520: 0: 1 0xa5 1023: 15:63 524160 524160
...
default_selection=F1 (Slice 1)
so it seems that someone is preventing changes to the partition table!
btw, this problem was not present in older boot0 (1.0) where the active
partition flag is ignored.
help needed here!
