Bios Mods -The Best BIOS Update and Modification Source

Just for kicks and giggles, show  me what you use.

I use Nano USB programmer - https://www.ebay.com/itm/271313593344
He has solder type and solderless adapters (similar to clip, but it's PCB jumper you push onto pins of BIOS in place)

If you get one of those, you need solderless, here is that kit -https://www.ebay.com/itm/271313593347
The second image shown in the listing gives an example of how it goes down onto chip only it's showing reverse since you're putting chip into it in that image. And none of his images match current stuff he's selling, it's all smaller and more updated. Just message him if you plan to purchase and tell him you need Programmer + solderless SOIC8 to DIP8 adapter + Solderless SOIC8 with spare 64MB chip (usually already included in price).

He used to sell just all the tiny adapters for $2-4 and I picked up a bunch to use different ways, now it looks like he only offers the DIP8 to SOP8 adapter by itself for $2 which requires you to solder BIOS on/off, the rest of the adapters are all in random kits and not ideally packaged for some uses. How I mainly use is similar to "Usage 4" in this listing, but no cables are required and the adapters are not like shown, I think all dated images here too (He has solderless SOIC8 to DIP8, which this example says you need SOP8-to-DIP8, can use either way) https://www.ebay.com/itm/271307536331

Here's images I've taken for others, showing the adapters in use

And here's all my adapters etc for this device, some solder type and some solderless, I picked up 2-3 of all the little adapters over past few years


I know that's a lot of random stuff and listings, items/examples etc, that's why I said it's better to just get the $2.xx CH341A and a SOIC8 test clip cable and be done with it all, much easier to get the right stuff first time and not have to wait on second shipments. And speaking of that, be sure you get the 1.8V adapter I mentioned previously too, you'll need it unless you end up with a programmer that can do 1.8V chips (cheap CH341A does not, without the adapter)

So if I wanted to use one of the Nanos I could connect a couple rows of 4-pin "pin headers" to the 16-pin DIP socket behind the PLCC socket, attach the ribbon cable or Dupont leads from the clip to the pin headers and call it a day?  Or do I have to make use of an adapter that uses the PLCC socket?

Sorry wasn't clear.

Thanks, Steve

I know it wasn't clear, since it's really the worst option in your situation, that's why I never suggested it really and trying to explain it only makes things worse so I rarely link to this

I've never used the headers on the back, so not sure how those are pinned out, but I assume you might be able to cable to them once you ask him for the pinouts. The normal way to use it would be connect your SOIC8 cable to the DIP8 socket in the middle of the programmer, same as you would for a cheap CH341A programmer. PLCC32 socket never used for anything except for PLCC32 chips.

So yes, I never thought of that since you have clip already, it would be same as if you purchased adapters, connect it to the middle of the programmer at the DIP8 socket with a DIP8 PCB and cables that are made for the SOIC8 clips (Or directly into the pin holes properly, DIP8 PCB adapter ideal since those holes are large), connect clip to chip and then call it a day. If you get this, since you have clip already, use the first link I gave you it's the cheapest option, or this one has the faster shipping (Both cheap and fast usually 12-14 days to US, sometimes faster as you know with any good China/Korea shipping sometimes can come fast) https://www.ebay.com/itm/281126398898

I swallowed hard and went straight to the link for the CH341A you first sent and bought it. Doesn't cost anything, just hard to believe something that absolute dirt cheap will actually work. Very hard to believe -- like they're almost giving them away. I guess I got so wrapped up in this having to work perfectly I didn't want to compromise on any chance it could go wrong.

I'll get it before the end of April. I paid the first level of shipping which shaved 10 days off free shipping, but if I bought it when you first told me I'd still be waiting almost that long anyway.

Oh, well.

BTW, Macronix sent me a link to this when I aksed them what they recommend...

Only $285.00, yikes!

So I got a backup plan at least. We'll see what Kee Electronics says about my CMOS chip.

Yes, the tiny cheap CH341A work just fine, I use them and help lots of people use them all the time.
You will need the 1.8V adapter for your BIOS chip to use with it - https://www.ebay.com/itm/202046860676

Wow $285 is insane amount, I wouldn't pay that if I was a millionaire, especially since $2 programmer works fine with $3 adapter
I guess it is better than $1,600 though https://www.xeltek.com/universal-program...rogrammer/

These are what I consider getting up there in price, but many suggest in various places

Similar kits with less goodies, EZP2010 and EZP2013 (usually $15-20), it's all China made stuff though, so if you order from China it's much cheaper

I just now ordered the 1.8v adapter but it's going to take forever to get to me.

Late April all the way to mid JUNE.

Oh, well.

Part of why I hate ordering from China so much, besides the no-name nature of almost everything.

You can probably find those adapters at Newegg or Amazon, I didn't check but I assume so since you can get the CH341A's there.

I like China orders, place them and forget then you get surprises in the mail

Surprise!  Did you remember ordering this?

 

I'm just kidding of course!

No, I don't remember making order for these, but I have two $2.50 CH341A programmers here, one green/blue and one black/gold
