Hi!
> This is interrupt calls for using PCI devices. Well you normally do not have to do anything special to just USE them in DOS, but the interrupts help to FIND and CONFIGURE them, in case they do not provide compatibility to standard devices such as VGA :-) You probably want to configure your disk controller to use not AHCI, but some sort of classic SATA if you want to use the UDVD driver or faster-than-BIOS access to your harddisk or SSD with other drivers. However, you do not need AHCI drivers in DOS at all if you just want to access your harddisk or SSD, as the BIOS already contains the drivers for that :-) Also, you do not want to write a DOS driver for AC97 or HDA sound, because sound drivers are not part of DOS: They are part of the games and very few games let you replace their sound drivers with your own. But you can use software like MPXPLAY to play media files in DOS while using the HDA / AC97 sound driver built into the software (MPXPLAY etc.) itself ;-) Regards, Eric > http://www.delorie.com/djgpp/doc/rbinter/ix/1A/B1.html _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
