I want to write DOS a program that is capable of Reading and Writing
to an iRMX-86 formatted floppy. iRMX-86 is Intel's OS and the problem
is that the floppy uses 26 sectors/track 128 bytes/sector, which is
not supported in the PC. 

I cant see that the BIOS can help me, so I must write a driver that 
talks to the FD controller directly.

Can anyone help? I dont have any information on the controller, except
that it is a NEC chip. Perhaps there is some public domain software
around that does something similar.

Any information or advice greatly appreciated.
