+FDCWriteBlks was patched to check the write-protect flag before attempting to
+perform a write operation. If set, the function throws an exception. I then
+discovered a error in my bit test where I used a hex bit mask instead of a bit
+position (which is what BT uses).
+
+BlkDevInit was patched (BlkDevInitFDC.HC) to add support for the floppy devices,
+as was Let2BlkDevType, which reassigned letters W-Z for floppy drives instead of
+optical (Let2BlkDevTypeFDC.HC).
+
+Mount2 was patched (Mount2LtrsFDC.HC) to reflect the above change to the drive
+letters. The patch file was initially erroneously named Mount2Ltrs.HC.
+
+2026-06-08:
+In Mount2CaseBFDC.HC, default parameters were added for convenience. From
+testing with the legacy driver, these worked well on my 3.5-inch high-density
+drive. The manual configuration instructions were also re-worded.
+
+2026-06-07:
+DskFDC.HC received a change to its sector size logic so that it works properly
+with the largest-size sectors (16 KiB), albeit of limited benefit.
+
+Three new files, Mount2{Vars,CaseA,CaseB}FDC.HC, were added to patch the Adam mount
+code to add floppy support. As the names of these files imply, they patch the
+Mount2 function (in ::/Adam/BlkDev/Mount.HC).
+
+2026-06-06:
+The block device type list in KernelA.HH was brought out to its own header file
+(KernelAFDC.HH) for ease of modification. The list of strings for the block
+device types was also brought out in a similar manner (KDefineBDTs.HC).
+
+BlkDevAdd has been patched to handle the new floppy block device; like the
+above patches, this one is also in a separate file (BlkDevAddFDC.HC). This
+file was later patched again to remove a forced assignment to 0 of the drive
+offset (as BlkDevAdd will set it to 0), and once more to add RedSea boot sector
+detection.
+
+Instructions on implementing these and any future patch files are currently
+only present in the Git log; proper instructions will be written later.
+
+In DskFDC.HC, a new function was added to test for the presence of a disk by
+checking for valid sector data. This avoids emulator-specific issues with the
+Disk Change flag.
+
+2026-06-04:
+The controller version check is now only done on the first drive when it is
+initialized.
+
+The data rate values accepted by the controller are now in KFloppyA.HH, as a
+courtesy to programmers. A new header file, KFloppyB2.HH, has been created to
+temporarily hold the headers for the new driver functions.
+
+The size of the DMA buffer has been reduced by half (to 9216 bytes), as part of
+a transition to single-track, single-head reads and writes.
+
2026-06-01:
I have removed the DMA flag from the CBlkDev patch as I have decided to only
support DMA at this time.
