The legendary BX chipset is back! Aopen AX6BC (New) ~ $29 @ Compgeeks.

Yeah, it is old chipset!

$29 Aopen AX6BC @ Compgeeks.

And don't forget 10% discount code!

--------------------------------------------------

I remembered the time I was at computershow and asked for this board and no one has it. I could only find it @ online!
 
boy that sounds like fun...painting between cpu pins with conductive paint 😉

Good link for those with steady hands, iluvdeal
 
That's a pretty scary mod...Not for the faint hearted or those
without very stable hands...

Also not for BX slot 1 boards, obviously.

Kwad

You could use a slotket, the mod is to the cpu itself.

 
I like the pin mod... sure would be nice if there were an easy way to modify a slotket to do this (I can't figure out how I'd disconnect/remove those pins).

That would be pretty easy with a slotket. Just tape over the appropriate contacts on the slotket's edge card connector. I used to do this all the time for the "B21 mod" that required taping over the B21 contact to allow some mobo's to run a 66MHz CPU at 100MHz.
 
These were good motherboards, but it's worth mentioning that some versions (think it was version 1.x) use a different clock generator, and so can't do the 1/4 PCI divider. I'm guessing that the boards they're selling aren't this older version, because the picture shows colored parallel port connector, while the older version had all black connectors.

Suprizingly, AOpen is still releasing new BIOS for these, last one was only a few months ago. I sold one of these a couple months ago, had a Celery 600@927 in it. There was some instability in mine at extremes of CPU core... Ran fine when i tried a Celery 1GHz@1GHz, but a Celery 733 o'c to 1185 wasn't at all stable, while that chip ran at same o'c speed fine in a newer Gigabyte/Via 694X board.

One minor annoyance is the floppy connector, is placed to the left and below the processor slot, making the only neat way to set it up being to use a really long floppy cable installed under the board before it's mounted in the case. Also, mine didn't have voltage adjustment either, but no biggie if you have a decent slotket.

While this is a fair deal, expecially for what looks to be a retal-packaged board, I'm wondering if it would be better than one of those Newegg refurbed socket 370 boards, which could work out to about the same price (or lower) when you consider the slotket cost for the AX6BC. Many of the cheapest Newegg refurbs are the Via 694X though, not the 694T... anyone know if the BX-Tualatin mod would work on other chipsets, using the same or different mod?
 
As seen here, you need at least BIOS version 2.47 to officially support Coppermine processors. I don't know if the motherboard would POST with older bios and a Coppermine, but that's likely irrelevant, since the box says "Coppermine" on it, it's pretty likely these motherboards already have at least version 2.47.

Should run up to PIII 1-1.1GHz w/100MHz FSB ONLY (unless you are pretty confident in overclocking a BX motherboard), or the more common PIII-850, or any Coppermine Celeron (up to 1.1GHz). AOpen's website mentions "Certain lot numbers are recommended", but mine was't one of the recommended lot numbers, and it didn't seem to matter.

bambam, I bought one of those slotkets from Newegg a few months ago, and although it said it supported FCPGA, it did not... The voltage settings for the jumpers didn't even go low enough to support Coppermine processors. Like an idiot, i thought that if i just left the voltage set to "auto", then it would work with a Coppermine Celeron. Big mistake! Apparently one of the VID pins is permanently connected, because it fried the processor in about 1/2 a second, didn't even take long enough to see smoke or any visual damage to the processor.🙁
 
I have one of these boards from back in the day, and the acpi support is nowhere near the iwill kk266 i also own. if you want acpi functions with your board, i would recommend picking something else.

I have heard mixed things about the revisions of the board. i would have a hard time believing that they are still making the revisions of the board that won't work with c-mine.

The only ACPI feature I have any interest in is safe shutdown via power button. Does it at least do that?
My Abit BH6 does, but the BH6 seems to be incompatible with the keyboard I want to use so I need a different mobo.
