DMA: Implemented autoinit mode in the PS/2 MCA side (although the bit is undocumented in said side, but documented in the ISA/PCI side).

Networking: Added the WD8013EP/A MCA nic, which is more supported than the WD80x3ET/A plus an initial ram size configuration before POS configuration.
Sound: Added the Reply MCA OEM of SB16 with its own MCA POS ID and properly implemented the IRQ's and DMA's of the AdLib Gold in its EEPROM plus an initial configurable setting for them and an initial DRQ implementation into said card.
