ATA/IDE disk access using PIO and interrupt

[Yan Luo]

Hello Thomas,

I still have a question. When you said "works like a charm", do you mean it 
works for powerpc/gen5200?

I don't see any irq.h or irq.c under c/src/lib/libbsp/i386/pc386. The 
interrupt vector BSP_SIU_IRQ_ATA is defined for powerpc/gen5200 in its 
irq.h, but NOT for i386. I don't think I can use that irq number for i386.

Any suggestions?

Thanks,
Yan
