Final (I hope
) EXDOS 1.4
Bugs fixed from the beta version: ATTR, ATDIR, and ISDOS (when not built in the ROM) commands now don't freeze
New additions:
-Most important: DISKIO now checking the presence of WD177x (with register write/read), then not needed anymore special non-floppy version for SD adapter
-For this new error definied (193): "Controller not ready"
-New error definied (192) for the Lost Data error reported by FDC.
-DISKIO now using fixed port addresses (1xh), then EXDOS ROM can be used at any segment number
-German and Spanish version with built in ISDOS now have the proper language version
-the original ISDOS command (which used in the not built in versions) have a bug, which is reported in old Enterpress article. Now it is fixed: it is reset the BOOT DRV variable if the ISDOS loading failed
-at EXDOS.INI handling added one more key: the Right SHIFT will force run EXDOS.INI. This is for the "go to the EP logo screen" reset, where the EXDOS.INI will not run at default
-in one floppy drive system will not search the EXDOS.INI on drive B: (drive B: are mapdisked)
-FORMAT will write modern boot sector to floppies: 32 bit disk ID also written for PC, added FAT12 filesystem identifier, and boot code modified for don't freeze PC if it is try to boot from EP disk
-separate versions for EXDOS card with WD1772, it is set the default STEP RATE to 3 which is faster (3ms instead 6ms). Now it is done at the early initialization of EXDOS, then the drive check before the EP logo screen also use the faster speed.
-the non built in ISDOS versions have a lot of free space at the second segment, can be combined with other EXOS ROM expansions (for example the HXC, we talked it about somewhere)
