Hi ,
I think the registers offsets of ICH7 are different from VT8237r, right? we need to use the data sheet of VT8237r. I also tested your code, it cannot boot.
In addition, thank you guys for help me out yesterday, and I solved the problem. I should put the smm handler code at 0xa8000(even implementation of ICH4 and ICH7 put the smm handler at 0xa0000, but the entry point is still at (0xa8000 - LAPICID * 0x400), and they used a jumptable. ). Anyway, thank you guys (especially Rudolf's patch) pointed out that and helping me fixed the problem.
Best, Fengwei
