I have an old MITUSUBISHI MP286 desktop with a Phoenix 80286/80386 ROM BIOS PLUS Version 3.10 00 BIOS. How do I enter the bios to change settings for hard disks/FDD? Also, does someone have a guide to the dip switchs? Thanks

Hi Poseidon. http://www.phoenix.com/en/customer+services/bios/bios+faq/default1.htm Take care, Linda

From XLWH post. "For information on running Setup, see your computer manual for directions, contact the maker of your computer or motherboard, and/or review the BIOS reference documents available on this site. Setup is usually run by pressing a special function key or key combination during POST, before the operating system is loaded. During POST, the BIOS usually displays a prompt such as: Press F2 to enter Setup If your computer does not display such a prompt, consult your owner's manual or contact the manufacturer for instructions. Your computer manufacturer may have selected a different keystroke sequence; the following sequences are commonly used: Ctrl+Alt+S Ctrl+Alt+Esc Ctrl+Alt+Ins Note: If you press the keys too early, the BIOS may display an error message. Not every BIOS has a built-in Setup program. Some older computers, such as 286 and early 386 models, require running the setup program from a floppy disk (supplied with the system when purchased). If you have such a system, you should be able to obtain a replacement diskette from your computer manufacturer, a local computer repair shop, or from eSupport.com (for Award BIOS). Phoenix does not sell or distribute Setup disks." YO

These are the most common: F1 F2 F3 F10 esc del ctrl+alt+esc ctrl+alt+s ctrl+alt+ins ctrl+alt+del

YOYO makes the best point here I've seen him make since he showed up... "Not every BIOS has a built-in Setup program.

Other manufacturers more or less followed this setup too. At this point, I'm not sure what the user had to do to configure an MP286 but I'll try to find out. If you can provide any other info on this rig, it may help. Serial number, info in user manual, is DOS 5.1 original OS on this rig (likely is), history of any repairs...anything you can think of.

I don't have much info about this system, since I received it free (someone threw it away). In any case, I don't think DOS 5.1 was original OS since it is IBM DOS from 1991. Cannot find a serial number on the system or inside of it.
