Hm,
The reason for the: noapic acpi=off
is that I don't know how to make the acpi part for my board.

And noapic?

Your mptable says it's virtual wire mode, but that won't work with noapic.

coreboot on "acer aspire 1520"

hehe,
I always thought that this is the same, my fault.

Ok, so I have probably also a bug in the mptables
because without the "noapic" it hangs in the same place, yes ?.

Hi,

You have the hang with coreboot already running?

How did you setup the northbridge?

Maybe just fixing PCI-ids to K8T890 may work (no K8M890).

Most of the regs looks similar! Just looking at their values

Also, if you need to have APIC working you need:

1) set the APIC to FSB mode
2) set the VT8735 to APIC mode (might be already check) 0:11.0
3) set correctly the bypass de-assert message - some reg 0:11.0
4) set correctly (force A2 from APIC FSB to low) some reg 0:11.0

You need to setup correctly also 0:0.7 offsets 0x70-0x7f

Otherwise it will not work.

Basically call vt8237r_cfg
and disable vt8237r_vlink_init

I will go on holiday tomorrow afternoon,

Rudolf

No, I have still problems :(
> How did you setup the northbridge?

I basically used the K8T890 and the vt8737r as the southbridges
(I'm avoiding the code for vt8735 because it dose not always work)

Also, if you need to have APIC working you need:

Ok, thanks a lot for the hints
I will try this at this weekend,
see what happens
