-------- Mensaje original -------- Asunto: Running (Free)DOS from ROM Fecha: Fri, 5 Aug 2011 10:08:37 -0700 (PDT) De: Ruud <ruud.baltis...@gmail.com> Organización: http://groups.google.com Grupos de noticias: comp.os.msdos.programmer,comp.os.msdos.misc,alt.os.free-dos Hallo allemaal, I'm hobbying more then a bit with some old IBM PC-XT (compatibles). And I found an old REX EPROM card capable of handling up to sixteen 27512s, good for 1 MByte of data. IMHO enough to contain the most used files of FreeDOS or MS-DOS. But how to do it? I know I need a kind of device driver to tell DOS with what device, in this case the EPROM card, is dealing. Problem: drivers are only loaded _after_ various other files have been loaded. The PC knows this because the BIOS contains info how to deal with a floppy drive. Or with an hard disk drive thanks to the EPROM on the HDD card. Having written my own BIOS which I can adapt to my own needs, I won't need an extra EPROM though :) I'm sure I could figure it out myself after some time (I think) but if anybody has done this before and wants to share the knowledge, I would be very pleased! Thank you very much in advance!
