Revised: 31-May-2007 This document contains a listing of mainboards and floppy controllers that have been tested with my TESTFDC program to determine their capabilities. I am hoping to grow this list, so please contribute your TESTFDC results for boards not already listed here. Usual disclaimers apply - I can make no guarantee that the information is correct, additions and corrections are welcome. ----------------------------- Useful Information -------------------------- All mainboards should pass the 'D' tests - these are required for standard PC formats. A mainboard that fails all 'S' tests will not be able to read or recreate single-density disks, which account for a significant portion of older non- PC formats. A mainboard that passes the 250 and 500kpbs 'S' tests, but fails the 300kbps 'S' test will not be able to handle single-density with a 1.2M 5.25" HD drive (the most common 5.25" drive types in AT and later machines), however it will be able to do it if you install a DD drive. (Use of a DD drive is recommended for SD/DD formats anyway, even if the HD setup supports it). The 'X' test (Double-Density with 128 bytes sectors) checks a capability that is used by very few disk formats, and for most people, not having it will not be a significant drawback. (Which is good, because the original NEC-765 PC controller, and most later chips based on this design don't support it). --------------------- Mainboard / Controller Listings ----------------------- S = Single Density P = Passed D = Double Density F = Failed X = Double Density / 128 byte sectors N = Not tested Data rate 250 300 500 Manufacturer Model FDC chip Class SDX SDX SDX ----------------------------------------------------------------------------- Abit KT7A ?
