This folder contains the files required to create a bootable FDOS-III system running on an FD360 or FD3712 disk system from iCOM (Pertec). FDOS provides four logical I/O devices: console, reader, punch, and list. The command processor on this disk (EXEC) defaults all four of these devices to the first port on an 88-2SIO serial board (I/O address 10h/11h). Through SYSGN parameters saved in sector 1, track 0, EXEC can be configured to assign different physical devices to the console, reader, punch, and list devices. Further, the EXEC init procedure can also load custom code specified during SYSGN. This would typically be the custom code for I/O devices other than the default 88-2SIO device. A good spot for this code is 2000h-20FFh. On an Altair 8800 (or other S-100 computer) with an 88-2SIO serial board, run PC2FLOP to create a bootable disk. See the "Disk Image Transfer" folder.
