Research suggests that ACPI breaks ISA floppy in Windows XP... I wonder if ACPI is breaking Freedos 1.3 as well?

A possible problem is that I am on an EVOC single board Pentium 4 computer that is designed for USB floppy drives. INT 13 sounds like a BIOS thing where the EVOC undoubtedly does NOT have the traditional BIOS. The EVOC is the FSC-1714VNA model. My passive ISA/PCI PICMG 1.0 backplane is undocumented. It is an HPP 14S. There are two jumpers on the backplane. One has been changed which is near the ATX connector on the backplane, the other appears to have something to do with the PCI bus. The only format I have achieved is with a Teac USB floppy drive in Windows Millenium, the ISA card not installed at all. Can someone shed light some light on Error 136 and DMA troubles?
