* Zet working at 25 Mhz without any visible problems...
* Implemented a simple PIC and Timer to receive both IRQ0 and IRQ1
* Hard disk implementation:
* Compact Flash controller through sysace (thanks to Sébastien
Bourdeauducq)
* int13_harddisk() function with read/write support
* int 19h implemented for hard disk
* Fetch simplification for NOP instruction
* Simulation model for the multiplier |

Implemented partial BIOS service int 1a (function 0), in order to prevent FreeDOS from doing weird things after a while.
With this bug corrected, there are no open bugs. |

Major flaws corrected:
* XCHG and SAHF microcode corrections
* Synchronized 'inta' signal with interrupt flag and 'intr'
* BIOS pusha 8086 transformation correction
* Decoder corrected for: CMP, ADD, ADC, SUB, SBB, XOR, AND, OR with i
* Implemented functions 08, 09 and 0a of int 10h
* Keyboard BIOS interrupts int 16h and int 09h now working
