Hello, I'm trying to use SeaBIOS, but it's stuck at timer init. I've located the problem at line 71 in file src/hw/timer.c. It tries to write IO register 0x43 and freezes.
Do you have any idea what could be wrong ?
Test system: * Intel Pentium CPU G2130 * Gigabyte GA-B75M-D3H * SeaBIOS 1.7.5 and SeaBIOS git f24eb2f853d4aa28814761e0bbc7df78149f8029 * coreboot default configuration
Kind Regards, Patrick Rudolph

Test system:
- Intel Pentium CPU G2130
- Gigabyte GA-B75M-D3H
- SeaBIOS 1.7.5 and SeaBIOS git f24eb2f853d4aa28814761e0bbc7df78149f8029
- coreboot default configuration
Can you send the full debug log of the failed boot?
A failed write to 0x43 sounds very odd - it could be an incomplete hardware configuration in coreboot, or it could be the legacy timer is not fully supported on that board (though that seems unlikely). You could comment out the call to timer_setup() in post.c and see if the boot progresses further.
