Such disks would have to be "installed" into DOS. The BIOS never did handle CD/DVD units directly, thus SHCDX33D always installs its units into DOS. However, the BIOS does handle hard-disks, and DOS "discovers" how many hard-disks the BIOS found during system boot. So, UIDE does not have, nor does it usually need, drive-installation code for hard disks. UIDE could have logic permitting a user-specified controller (i.e. an "add on" card) and could install disks/CDs/DVDs for that controller. But few people have "add on" cards, it is not the best use of my time. It also increases the size of UIDE/UIDEJR. UIDEJR is about 30 bytes from going over 4608 bytes "packed" via UPX (9 sectors on a "boot" diskette). I will add AHCI logic when needed, but I must be "guarded" re: other driver additions! ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
