diskaccess from pmode without bios

Unknown

Hi!

I'm coding on my own OS and I want to access the hard/floppy disk without switching to rmode and call bios.

Do you know how Linux handle these problems?

If you know something that you think i should know, then post a message.

I'm not exactly sure how Linux or DOS extenders deal

with problem, however, you could probably control the HD

yourself via the ports, if you simply dumped the BIOS

interrupt.

www.seagate.com and www.maxtor.com have some refereces if i remember correctly. I have a book The Undocumented PC (a programmers guide to I/O, CPU's and Fixed Memory Areas). It's up to date with MMX, and a AMD 3-D now version is due soon. ISBN: 0-201-47950-8 Author: Van Gilluwe. Addison Wesley Developers Press. This book is a must for any serious ASM developer. ( it also describes how to access drives with the controlers registers and ports.)
