Thank you! So based on that I guess it is a step B0 engineering sample. (It's weird they used the letter "O" and not a zero.) That's great news then. Not only is it one of the early buggy 386s, it's an engineering sample too. 😀

I have this i386 chip (see pics) and it's clearly an early one since it has no DX designation, lacks the new logo, and only has the 1985 copyright date. Does the "ES" mean it's an engineering sample? The "BO" on the first line has the letter "O" and not a zero, so I don't think it's implying it's a …

Does that include Cyrix compatibility or does it need to be TI specifically?

Before I try to use the chip in a 486 motherboard I am wondering if anyone here knows if it's as easy as plugging it in and setting the right jumpers. Can I just drop the chip in or does it need a custom board or something else? Thanks!

Probably some aftermarket cooler that have been glued on there ? It's possible, but it doesn't look like a generic aftermarket cooler. I have a number of chips with the typical 486 heat sinks but they are all nondescript. This one is so close to the ones Intel uses form the factory that it made me …

A couple years ago I bought a small lot of interesting/uncommon CPUs from someone selling their collection. All of the other chips were easy to identify, but this one is a bit odd. Does anyone have an idea of what it might be? (As in, what S/Q-spec/version it might be.) Here are a few observations: …

@rikukos Awesome! That's a great find. @Murugan same here. I have pictures from Christmas morning when I got my first Sound Blaster in that box. It's long gone, sadly.

kithylin, that's pretty much accurate. Unlike video cards and IO cards, sound cards lack an option BIOS and there is no way at a low level to communicate with the card unless the driver, application, or OS is PCI-aware. An old game, for example, can use a more modern graphics card because it can …

I used to use these boards a few years ago. They are very stable and work well for embedded applications. Having said that, happycube is correct in that the -M boards used bad caps. I also found that some EPIA models were very lacking in driver support for non-XP OSes.

Thanks. I did find this: http://stason.org/TULARC/pc/motherboards/M/M- … 18-PCI-486.html It's a bit confusing because it lists the 72-pin RAM as x36 and the 30-pin RAM as x9 so that implies it needs parity (ECC). That seems odd to me because it's not a server board.

Hi all. Does anyone have the RAM specs for the M-Tech R418 486 PCI motherboard? Also, for those of you who own this board what has your experience been with adding L2 cache? (Especially up to 1MB) Thanks

Odd that a PIII era board would have problems with the 500mb limit though... Agreed, especially an Intel board with AGP. I have an earlier Intel Pentium II board that can see past 500MB so needless to say I did not expect this problem on the motherboard. For some reason Intel no longer lists this …

CF cards can have issues with some BIOSes, particularly older ones. To take one example, PhoenixBIOS used on 386 laptops can't boot MS-DOS, because >~512 byte reads will hang. On the other hand, 386BSD or LILO and GRUB bootloaders do work with these. Your post was perfectly timed. :) Last night I …

It's really odd that Windows XP setup allows you to partition the drive, but DOS 6.22 doesn't even see it... Yeah. I found that ... odd. I really wish I knew why. I'm sorry but I'm out of ideas... Thanks for the info. 😀 Anyone know why this could be happening?

You can use Puppy Linux or Knoppix to change some flags of the CF card. How exactly? I thought those flags were CF-card specific and only manipulatable using vendor tools? (Like SanDisk's leaked ATCFWCHG.COM.) Also check if there isn't a disc overlay software or something similar installed. Indeed. …
