add CHS param checking (FDC), fix DMA address setting (DMA_XFER)

• Tue, 14 Dec 2010 02:41:40 +0000
• by Philip Pemberton <philpem@philpem.me.uk> [Tue, 14 Dec 2010 02:41:40 +0000] rev 57

  * Floppy controller wasn't checking CHS values. Fixed.
  * DMA ADDRESS COUNT register was implemented completely wrong -- shifts and ANDmasks were wrong. Fixed.
  
  Boot PROM and Loader now run to the point of booting the kernel!
