A 486 motherboard I have that is based on the Opti 495SX chipset does not seem to have any options in the BIOS to enable/disable memory paging-interleaving. Benchmarks indicate no such scheme is running. I find this rather ridiculous, because I thought just about all 486 boards used these modes.

I remember several years back I was pretty sure I read somewhere that it is possible to use some kind of BIOS utility that lets you enable/disable features supported on your board that are not listed in the CMOS setup. Am I just hallucinating or is this possible?

The link on this page is dead but I wonder if it's worth tracking down the utility mentioned:

Think I'll have a look for it later myself - I've got an Opti 495 board with ami winbios.

Hey, thanks. I found a working link:

I remember I had this program at one point, but it was years ago and I forgot the name.

If it's a flash BIOS, then there is a utility called Modbin, which can edit the ROM file and possibly unhide hidden settings. There's also Award Bios Editor, but I haven't used it.
