- store r/o disk timestamp in FAT format in reserved field of redolog header
- use the VVFAT function fat_datetime() to convert the mtime value
- update redolog header if timestamp is undefined (first usage)
- Bochs now panics if the r/o disk has been modified after the first usage with
the undoable disk image mode to avoid journal file corruption.
- undoable: fixed r/o disk size check
[Bochs-developers] [Patch #3539228] Part 3
> Added dummy EOI handler and all unused IRQ vectors set to this.QEMM 97 does not crash any more.
Looks good. Those "SET_INT_VECTOR comments" should be removed.

- use this feature for floppy read and write operations. This does not mean that
the floppy now works faster than realtime, but it reduces the number of DMA
calls from the CPU.
- removed outdated file: patch.fast-dma-cbothamy
- TODO: implement this feature in the SB16 (8 and 16 bit)
Instruction Set Extensions
Programming Reference
rev013
was published including RDSEED and ADCX/ADOX instructions
add CPUID bits and VMX controls mentioned in the document
- Changed to frequently using segment base to DS based - Added set_DS function
(Set DS value,returns old DS value),(read/write)_(byte/word/dword)_DS macro
to refer DS segment based data.
- Almost BIOS interrupt handler wrapper changed to DS base to use DS-based
reference macro effectiently.
- Merged ata_cmd_data_in and ata_cmd_data_out function to ata_cmd_data_io
- Merged INT13 AH=02 and AH=03 I/O routine
- Modified cdrom_boot,int15_function,set_e820_range and pci/pnobios low level code to more optimal
- Deleted INT1C handler that duplicated with dummy_iret_handler
- Added dummy EOI handler and all unused IRQ vectors set to this.QEMM 97 does not crash any more.
- Changed INT15 AH=80,81,82,90,91 functions to return success.
- Added INT71(IRQ9 - Redirect to IRQ2) handler.
- Some IRQ handlers call INT15 with AH=91.
- INT16 handler calls INT15 with AX=9002.
- Fixed IRQ14 handler that overwrites 40:8F to 00
- TODO #1: fix pcipnic / pnic name problem to support direct plugin loading
- TODO #2: automatically assign PCI-only devices to a PCI slot if not already done
