Because in the PC-98 of the 8086 CPU era, the HDD was SASI or SCSI, but there are many types of host adapters including third parties, and the SCSI on hand is made by a third party and only a limited number of people can obtain the BIOS for this. Also, I don't have a genuine NEC SASI / SCSI host adapter, so I can't get the BIOS. I might have disco...

FDD code is on FPGA. The ARM side only inputs and outputs files, and the FPGA expands the .d88 image to the track image. The .d88 format is used because ...
