Hello all,
I have some troubles with my resource map on my VIA/K8 project. I'm working on K8T890 VIA / VT8237 MB with K8 939.
For some reason my PCI IO limit get set to 0x4000

I'm using my own resourcemap file which I'm attaching.
Anyone knows the reason why this register get overwritten? Is somewhere documented what needs to be setup in resource map and what get set up in northbridge.c of K8 and friends?
When I need K8_ALLOCATE_IO_RANGE ?
As for the status update. Linux runs with one DIMM because the interleaved is still? not supported for unbuffered dimms?
Peripherals seems to work, but the SATA/IDE will hang after heavy IO. I think it is because of not yet configured VIA V-link.
So far I'm booting it with FILO to initramfs based FS, details at the end of mail.
I hope my questions are more clear than my mind - need some sleep now.
Oh btw I wrote some K8 resource dump program. It is still alpha, but produces some results. Attached too. Suggestions wellcome! All files will be released under GPL one I get it working.
Regards Rudolf
