I am looking for references (or better yet first-hand info) about driving MFM, ESDI and IDE drives at the hardware (below-the-BIOS) level. If any one reading this posting has done any work in this area, I would appreciate any pointers in print or otherwise you could afford me. (I exclude SCSI because I have a good reference on this) I have a copy of the "IBM PC-AT Technical Reference Guide", which talks a little about the register structure of an MFM controller, but it does not go into _quite_ enough detail for me to figure out how to make it go. I would like: pointers to books pointers to articles (archived) the articles themselves or source code (;-)) OR anything else you may have that you think would be helpful. ================================================================================ -Jeff Evarts Fax: (916) 920-5306 --jde@unify.COM Phone:(916) 922-1177 ================================================================================
