Roana Technologies) Newsgroups: comp.os.386bsd.questions Subject: Why no std BIOS INT 13 HD support for crappy HD's? Date: 15 Jan 1995 19:06:23 GMT Organization: University of Twente, Dept. of Computer Science Lines: 18 Distribution: world Message-ID: <3fbrnf$7bd@utrhcs.cs.utwente.nl> NNTP-Posting-Host: solaris.cs.utwente.nl X-Newsreader: TIN [version 1.2 PL2] Folks, Please correct me if I'm wrong, but isn't it possible to write a generic Hard disk driver that uses interrupt 13 from the PC BIOS? Of course this will give lousy performance, but it seems to me that a lot of questions posted in this group would be over when such a driver existed, for users of non-standard SCSI adapters, for example. Why not access them the same way Messy-DOS does? Excuse me for not taking an in-depth look at the kernel sources, but do these BIOS functions offer too little functions? or is usage of these interrupts impossible/unwanted in the kernel sources? -- ROANA Technologies VOF roana@cs.utwente.nl P.O.
