1. Implemented as best as possible the MDL S/G required by NeXTSTEP/OPENSTEP, fixes detection of storage devices.
2. Timer bits from the Clock registers are now implemented.
1. Too many soft resets should not reset the SCSI layer, fixes CD Audio on the 53c90a MCA controller used by guests.
2. Implemented preliminary MDL S/G mode for the PCSCSI side.
3. The underflow DMA function is no longer needed as it now SCSI transfers on the 53c90a MCA controller works properly.
4. Minor corrections to the PCI side (mainly the revision).
5. The DMA 86c01 side of the MCA 53c90a controller is more polished now, should fix some more bugs.
SCSI CD-ROM: request sense command should preserve its sense data unless a different command is issued, fixes DOS hanging with a blinking cursor using CDSCSI-2.sys for the 53c9x MCA card when there's no CD inside, making its no length Data In hack no longer needed.
This commit should fix the NT 3.1 AMD PCscsi drivers when they look for devices on LUN > 0 and causing havoc with them (BSOD).
Basically clear the FIFO and set the SEQ_0 bit in the RSEQ read reg.
AM53c974 side: a biosless card is biosless.
General: fixed all the log excesses.
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.
Roughly implemented the SCSI IDENTIFY message LUN operation, fixes some SCSI controller drivers in some situations;
Added an undocumented CMD640 IDE controller register required by Linux and by a DOS driver.
Moved the DC390 timer initialization to the Flush write command, where it takes a higher priority, fixes NT 3.1 DC390 specific drivers while keeping the AMD branded drivers intact.
Changes to device_t struct to accomodate the upcoming PCI IRQ arbitration rewrite;
Added device.c/h API to obtain name from the device_t struct;
Significant changes to win/win_settings.c to clean up the code a bit and fix bugs;
Ported all the CPU and AudioPCI commits from PCem;
Added an API call to allow ACPI soft power off to gracefully stop the emulator;
Removed the Siemens PCD-2L from the Dev branch because it now works;
Removed the Socket 5 HP Vectra from the Dev branch because it now works;
Fixed the Compaq Presario and the Micronics Spitfire;
Give the IBM PC330 its own list of 486 CPU so it can have DX2's with CPUID 0x470;
SMM fixes;
Rewrote the SYSENTER, SYSEXIT, SYSCALL, and SYSRET instructions;
Changed IDE reset period to match the specification, fixes#929;
The keyboard input and output ports are now forced in front of the queue when read, fixes a number of bugs, including the AMI Apollo hanging on soft reset;
Added the Intel AN430TX but Dev branched because it does not work;
The network code no longer drops packets if the emulated network card has failed to receive them (eg. when the buffer is full);
Changes to PCI card adding and renamed some PCI slot types, also added proper AGP bridge slot types;
USB UHCI emulation is no longer a stub (still doesn't fully work, but at least Windows XP chk with Debug no longer ASSERT's on it);
Fixed NVR on the the SMC FDC37C932QF and APM variants;
A number of fixes to Intel 4x0 chipsets, including fixing every register of the 440LX and 440EX;
Some ACPI changes.
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.
