DOS ain't dead

Is there some DOS floppy utility that doesn't rely on DMA? (Developers)

Well, I found that I passed linux kernel cmdline parameters wrong way to linld.com.
it shouldn't be
"floppy=0,4,cmos nodma messages"
but
"floppy=0,4,cmos floppy=nodma floppy=messages"
Then linux booted really in PIO (noDMA) mode and I was finally able to mount and read floppies :) A lot of them thrown bunch of various errors in dmesg but some read/write without any error. So I tested that my superIO HW solution works. Now I'd like to make it work under DOS too. It would be a challenge to write a TSR for int13h extension that use floppy nodma code so other dos apps could use via bios services to access floppy in std. way.

DOS gives me freedom to unlimited HW access.
