OpenBIOS/Sparc32 almost loading Linux - OpenBIOS

7 May 2006


      ESP works now, I had the memcpy arguments switched (brown paper bag time).
I added Sun partition table handling:
opening SBus
opening drive 2
ob_sd_read_blocks id 2 ffdc28d8 block=0 n=1
ob_sd_read_sectors id 2 ffdc28d8 block=0 len=1
sunparts_open '<NULL>'
ob_sd_read_blocks id 2 ffdc2468 block=0 n=1
ob_sd_read_sectors id 2 ffdc2468 block=0 len=1
a: 0 + 1193664, id 83, flags 18
b: 0 + 0, id 83, flags 18
c: 0 + 0, id 83, flags 18
d: 0 + 0, id 83, flags 18
e: 0 + 0, id 83, flags 18
f: 0 + 0, id 83, flags 18
g: 0 + 0, id 83, flags 18
h: 0 + 0, id 83, flags 18
Found Sun partition table, offs 0 size 1193664
ob_sd_read_blocks id 2 ffdc2198 block=2 n=1
It would be nice to have more than one partition table model (PC and Sun) 
supported at a time.
If I use a kernel file as a device image, OpenBIOS loads a lot of it but 
crashes before it's finished:
Loading image...
segment 0 addr:0x0 file:0x2780e0 mem:0x2a3828 loading... ob_sd_read_blocks 
id 2
0 block=0 n=5056
ob_sd_read_sectors id 2 0 block=0 len=1
--- clip ---
ob_sd_read_sectors id 2 12600 block=147 len=1
ob_sd_read_sectors id 2 12800 block=148 len=1
Unhandled Exception 0x00000009
PC = 0xffd0b7e4 NPC = 0xffd0b7e8
Stopping execution
I threw in some const qualifiers to make the data segment vanish, but there 
are still some.
