Two new error messages will be added to final EXDOS 1.4:
One are old error, without own message:
*** Lost data byte
This is directly from the WD177x (see the datasheet). It is happened when the CPU don't read the data from Data register before the next data byte arrived. It is can be happened with Turbo EXDOS, when HD disks used on non turbo Z80 clock.
(Previously this is translated as simple Data error)

Next is totaly new:
*** Controller not ready
It is happened when the WD177x can not accessed. For example using SD cartridge without EXDOS card :-)
Previously the EXDOS freezee at this situation. This is why needed remove floppy support from the SD ROM. Now controller check added, then not needed separate floppy and non-floppy EXDOS versions.

Any suggestions for German and Spanish translations?
I tried with google translate:
*** Verlorene Daten-Byte
*** Controller nicht bereit

*** Perdidas bytes de datos
*** Controlador no está listo

On a correct Castillian(one of the Spanish languages) I would like these messages:

*** Se ha perdido el Byte de datos or *** El Byte de datos se ha perdido
*** El controlador no está accesible

But then they would clash with the condensed messages of the ESP.rom. Better I select these:

*** Byte de datos perdido
*** Controlador no accesible

Final (I hope :oops: ) EXDOS 1.4

Bugs fixed from the beta version: ATTR, ATDIR, and ISDOS (when not built in the ROM) commands now don't freeze :oops:

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)
