Hi, i'm working with these mainboard fanless: Jetway NF94-270-LF
The bios chip is one Winbond W25X80, i have released a simple circuit with one transistor BC547, and the rest connected directly to the paralel port in mode ECP, data buses are 3.3V Also i have release a simple program to erase, test and program it. If one are interesed in this, tell-me. The flashprogram not works correctly with this chip, but i can try to solve. The CPU is the Atom N270, normally i used VIA's but, i will test my aplications with it, with VIA i cannot use my SSE2 optimizations, they are more slow that direct use of 32bit assembler code. This have a Fintek SuperIO F71862FG that is similar to the F71805F. The base is the ich7m and i945GSE. I have tested and make that it works, except the VGA and the Audio, i have solved the problems with acpi, and linux kernel boots normally with the SATA. I have only one problem, with the variable MTRR if i activate variable MTRR's for have cache, the kernel immediately makes a triple fault. I not known if in the moment of activate MTRR this chip generates a spurious interrupt or similar, and when the kernel creates the IDT table, hangs. Have one show this problem in the past? I have send to local APIC's the EOI, but the problem continues... -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
