  Hi Kevin,
 
 I have tried Seabios on my hp dl145 g3 (the patches from mondrian) and
 it works really well now
 I was able to load the vga rom and i have output on the screen.
Great!

  One single problem... It doesn't seem to find the
sata controller...
 
 bootlog with coreboot and seabios:
 http://merlin.ugent.be/~samuel/dl145g3/corebootwithseabios.log
There isn't much SeaBIOS info in that log - can you recompile with
CONFIG_DEBUG_LEVEL set to 6?

  
 lspci -vnn : http://merlin.ugent.be/~samuel/dl145g3/info/lspci-vnn.txt
 
 and the original patch from mondrian to add support for the dl145g3 to filo:
 http://merlin.ugent.be/~samuel/dl145g3/patch/filo_dl145_sata.patch
 
 It looks rather simple but I don't see what i have to change in
 seabios to support the device.
 
 The pci id (0x104 is already in pci_ids.h of seabios) so i would think
 it should just work. Myles thought it could be related to the fact
 that his sata interface of this mainboard does not support a legacy
 IDE interface mode.
 
 You have any ideas how i could quickly add support for the hp dl145 g3
 to SeaBIOS??
The equivalent patch in SeaBIOS would look like:

--- a/src/ata.c
+++ b/src/ata.c
@@ -841,7 +845,8 @@ ata_init()
     int count=0;
     int bdf, max;

I ran into this same issue when porting the dl165g3 board.  I was able
to get SeaBIOS to boot from my SATA disks by applying the following:

What S-ATA controller is that? We have a SIL 3114 driver which sets the
class ID from RAID to IDE in coreboot. Maybe something like that would
work here, too?

Not sure which is the better approach though.

This is the onboard BCM5785/HT1000 SATA controller.
