1. Add the original AMD 53c974 (AMD bios only and revision 0x00 compared to the A revision which is 0x10 in the PCI regs) as well as correcting the SCSI bus reset when prompted (ESP CMD 0x03), the latter fixes DawiControl 53c974 drivers on win9x.
2. Check if DMA length is not 0 for DMA transfers.
3. More logs for possible problem diagnostics.
Ported the latest changes/fixes to the above controller from QEMU and added a bios-less AMD Am53c974 device (non-DC390).
The latest changes fix the AMD-branded DOS ASPI drivers on both cards (even without bios).
1. Changed the MCA ID of said adapter to one that is add-on based rather than integrated (still no bios though).
2. Fixed the DMA/IRQ stuff of the 86c01 DMA side of the card.
CD boot-capable PCI SCSI adapter support.
Begin the process of revamping/separating the EEPROM used by ATI
which is the same as the one as the DC-390 does use.
