The network poller is now in its own thread;
The hack is back in the emulation of the National Semiconductors PC87306 Super I/O Chip - it's the only way right now to have serial working on that board;
Fixed a part of the code that was still using NukedOPL even when OPL 3 was set to DOSBox OPL;
Applied all mainline PCem commits.
SCSI DMA writes (for MODE SELECT) now correctly use InitLength instead of request_length when bus type is SCSI;
Fixed MODE SELECT page saving;
CD Audio volume is now correctly initialized on card initialization for all Sound Blaster variants, fixes CD Audio being muted when booting without the Sound Blaster initialization program;
Brought the Sound Blaster variants back to a sane sound volume but still louder than the old quietness;
Moved SCSI adapter initialization to before sound card initialization, fixes DOS SCSI CD-ROM driver hangs under some conditions.
Fixed a link-breaking bug in cdrom.c;
The AHA-154x now supports commands 0x28 (GET EXTENDED BIOS INFO) and 0x29 (UNLOCK MAILBOX) and no longer reports a firmware revision with scatter/gather bug;
The BusLogic now supports command 0x20 (RESET);
Fixed the GPIO register mapping on the National Semiconductors PC87306 Super I/O chip.
Improved the BusLogic incoming mailbox code;
The BusLogic callback is now three-phases and outgoing mailbox interrupts are emulated correctly;

Significantly rewrote parts of the AHA-154x and BusLogic emulation, NT 3.1 RTM and MS-DOS drivers now works correctly;
The function in cdrom.c to read data blocks from the disc now correctly advances the position of the sector to read in non-passthrough mode, fixes multiblock reads from directly mounted ISO's;
Both ATAPI and SCSI now always check for Unit Attention and Not Ready on command execution.
SCSI LUN is now selectable for the CD-ROM drives;
