Hi,
Unfortunatelly that doesn't work..
The observed behaviour of LinuxBIOS after the change is exactly the same as
before.. (I have no logs yet, I will post them this evening..)
After Linux boots (with LB) the PCI bridge (00:06.0) is still badly (or not!)
initialized..
In fact, I noticed a (very small) effect of the code change proposed by
Yinghai:
- before the change, the command:
setpci -s 00:01.0 78.l
gives the result:
20040000
- after the change, the same command gives the result:
19040000
This validates, I think, that my build of LB was correct, the programming of
the flash was successfull, and LB did indeed execute the initialization proposed
by Yinghai..
But the PCI bridge activation/initialization issue remains .. :/
Any ideas?..
Best regards,
Florentin Demetrescu
