I need an Enhanced BIOS to acces >504MB. How do I get one?
The options are: a new mainboard BIOS, add-on BIOS, or software. To upgrade your mainboard BIOS, either by a newer version of your current BIOS or by a custom made BIOS from firms such as Microid Research (MR BIOS), is probably the best option. It may or may not be more effective to replace the entire mainboard and get all the latest bells and whistles for $100 more. The next option is to purchase an add-on BIOS that effectively replaces the harddisk portion of your mainboard BIOS. Most BIOSes on ATA-2 interfaces, if they have a BIOS at all, also do this, so that may be a nice way to go if your present interface isn’t up to snuff. Either way, you will have to repartition and reformat the (large) harddisk. A final option is to use a software solution. Be sure to read the section about this below.
