Hello @tyama501, It seems there may be multiple issues, but certainly FAT file corruption seems to be end result. I am wondering about the following: 1) is problem related to...

Ok. It will be good to know whether 1232k works on floppy on emulator, then check 1440k floppy on emulator. Agree that issue could be 1440k floppies or hardware since...

If everything works well on emulator but not on real hardware, then issue could be related to new LOADALL. In that case, turn off XMS completely for real hardware testing...

Good to know it repeats on the emulator. How about floppy -> floppy 1232k copy, does that fail, or is this limited only to HD copy? We did update the...

@tyama501, how do you add a hard drive to DosBox-X's configuration file? I can only test PC-98 using DosBox-X, and have never done that. Their instructions say to use "imgmount"...

Hello @tyama501, I've identified the problem in #2390. Basically, makeboot -f never worked with fat.bin, which is why none of your commit rollbacks worked, and the system only worked when...

Can you please give me more information and/or screenshots about mkfat not working, as well as what you mean only working with older versions of ELKS? I can then debug...
