Depends on what bios version is on the board. According AL440LX Spec Update May 1999 on page 27: "The motherboard supports the Celeron processor at 266 MHz with BIOS version 4A4LL0X0.86A.0023.P08, or later. Earlier BIOS versions will identify the processor as a Pentium II processor and will not …

That's absurdly correct ! I have tested and it's the fan2 circuit. Thanks. I guess I will leave it like that. Do you know if this board is Celeron compatible without a BIOS update? I know this board predates Celeron era but I haven't a P2 cartridge here, with a Celeron SL2WN (333/66) I am getting a …

Got this motherboard that looks like it has a burned transistor. I cleaned it up but need help from someone who has the same board to identify the component. The board is a Intel AL440LX the version with the 2 Yamaha chips, I guess it is from a Micron Millennia SKU. https://i.imgur.com/vx7JglZ.jpeg …

I am using a combination of a Live CT4830 + Drive CT4860. I can get audio through the Drive headphone jack, which I assume it´s correct connected to the sound card, but no MIDI from the front panel.

What games are you seeing the switching behavior with? I also looked up in the manual is there is nothing in there about auto-switching to …

Mostly 486 became obsolete when Doom came out in 93. That's just your opinion, it's wrong. Would you not agree that "obsolete" would mean the inability to run most available software? By all accounts, DOOM was a pretty enjoyable game on a DX2 with VLB. At best DOOM made the 486 second rate to the …

Before 1990 (the 286 and 386 years), a lot of PCs didn't have hard drives. So actually an HDD was the ultimate upgrade for most people, not a soundcard. The 486 wasn't exactly a flash in the pan. It came out at the end of 1989, and was only obsoleted by Windows 95 (which was available at the end of …
