Update FAT.COM on ROM disks

The original release of v3.4 contained an out-of-date copy of FAT.COM on the ROM disks.  This **only** updates FAT.COM on the ROM disks.  Do **not** use FAT.COM from the original ROM disks.
- The copy of FAT.COM on the hard/floppy disk images was fine in the original release.  Only the ROM disks contained the out-of-date version.
- It is not necessary to update your hard/floppy disks when upgrading your ROM to this patch version.

+; CH376 SD CARD SUB-DRIVER
+;==================================================================================================
+;
+; Thanks and credit to Alan Cox.  Much of this driver is based on
+; his code in FUZIX (https://github.com/EtchedPixels/FUZIX).
+;
+; This file contains the SD Card specific support for the CH37x
+; driver.  This file is included by the core driver file (ch.asm) as
+; needed.  Note that only the CH376 actually supports SD Card access.
+;
+; The SD Card support is implemented using the CH376 file-level
+; support.  It is *not* possible to access SD Cards using raw
+; sector I/O.

+;==================================================================================================
+; CH375/376 USB SUB-DRIVER
+;==================================================================================================
+;
+; Thanks and credit to Alan Cox.  Much of this driver is based on
+; his code in FUZIX (https://github.com/EtchedPixels/FUZIX).
+;
+; This file contains the USB Drive specific support for the CH37x
+; driver.  This file is included by the core driver file (ch.asm) as
+; needed.
+;
+; The USB support is implemented as pure raw sector I/O.  The CH376
+; file-level support is not utilized.
+;
+; NOTES:
+;  - There seem to be compatibility issues with older USB thumb drives.
+;    Such drives will complete DISK_INIT successfully, but then return
+;    an error attempting to do any I/O.  The error is $17 indicating
+;    the CH37x encountered an overflow during communication with the
+;    device.   I found that adding a DISK_MOUNT command (only possible
+;    on CH376) resolved the issue for some devices, so that has been
+;    added to the RESET routine when using CH376.
+;
+; TODO:
+;  - Implement auto-recovery on error status?
