BIOS flash programmers. Which one is right for you?

[@Magsyboy]

Sorin explain these on his channel on ch341A when you put the bios on that when it power it on the 5v drops automatically at 3.3v when in use

[@xConundrumx]

Bios aside, I want to point out that the TL866 programmers (and the successors ...) also have the ability to test a bunch of IC's for proper function. If you work with older machines (retro stuff) you will appreciate that functionality once you get to discovering that feature. It might not do as many as the purpose built Retro Pro Chip tester but still useful to have.

There's some issues with the CH341a as it feeds 5 volts even you've selected 3.2 volts. Never versions have a some sort of switch, but still many sells the outdated version.

All i get on my little gold rimmed CH341A programmer using clip and diff bios chips are all READ FF's or all 00's so dont know whats going on.

Good explaination! Choosing the right BIOS flash programmer depends on your specific needs and technical expertise. For basic firmware updates, simpler, user-friendly models are ideal. However, for more advanced programming or multi-chip compatibility, investing in a robust, feature-rich programmer with reliable software support is essential. Prioritize models that support the chipsets you commonly use and come with good community or manufacturer support. Always consider ease of use, documentation, and cost-effectiveness to ensure seamless BIOS flashing and repairs. Then I came across GAO RFID Inc, which offers what you might find useful.

Great video! This helped me choose the right BIOS flash programmer! Thank you!

[@dzabakwesi2213]

Thanks for the knowledge and doing this review in English

[@aoi2853]

What about SPI? Only ch341a supports it?

[@lamar9525]

Why can't I find the list of the programmers?

[@anounceofbrilliance]

They are all listed in the in video description. They are available from Amazon and other online retailers.

[@FrancoPN]

Also to have the 3elloPorg is a good deal for quick service, as it is Off-line programmer doesn't need computer

[@reginanartates8365]

Still have?

[@Shepherd4R]

What interface would I use to read from a W25R256JVEQ? I'm trying to fix my laptop :/ That one is the only 32MB chip I could find. I'm not even sure that is the BIOS chip but every other chip I found was 256K - 2MB.

[@anounceofbrilliance]

The spec sheet shows this as a 266 Mbit 3v chip. I can only tell you what I would do.. I would really make sure there is an issue with the BIOS. Typically the BIOS needs to be customized, which is NOT an easy process. In my opinion reflashing the BIOS should be a last resort.

[@bobgames1984-s9q]

I know it's a noob question, but would the 2023+ be able to program plc32 chips? I was looking for something to program that specific type of chip and didn't see if it will work. 🙏 Thanks anyone who could help Edit...also, thanks for making this video.

[@anounceofbrilliance]

I'm almost 100% positive that the 2023 Plus will not program any pick chips. For pic programming I bought a PICKIT2 and it works great and was very inexpensive. I believe the T48 (TL866-3G) Programmer. which is the third one in the video can program most PIC chips although I never tried it since I have the PICKIT2.

[@bobgames1984-s9q]

@@anounceofbrilliance thanks for the reply. I ordered a t48. And then figured out how to flash what I needed to in place 😅. So I ordered another just to play with the programmer 🤣😂

[@suhailhabibzadah8634]

Does the TL866 programmer work these 3 chips? AT89C52, MC68711E20CFNE2, 93C66

[@anounceofbrilliance]

The unit I have in this video is a TL866-G3. The software shows the AT89C52 chip and the ACE93C66 (both x8 and x16 versions). So It appears it programs these versions. It did NOT show the MC68711 in the list. The non DIP version would require an adapter. The unit I bought did have some of these adapters included.

[@suhailhabibzadah8634]

@@anounceofbrilliance ok awesome! Thanks for your help

[@nbctcp3450]

1. someone said EZP2023 vs EZP2025. EZP2025 has more databases compare with previous one. is that mean if I connect unknown eeprom. chance to recognize it is bigger compare to old model 2. can I adding CH341 built-in databases 3. can I use SOP8 clip for CH341 in EZP2023

[@caralynx]

FWIW CH341a is merely an interface bridge, so if you can write software to interface with it, you can support whatever you like. The most common programming software for it is open source, so if you need something special you can update it yourself. When you're buying a programmer, try to find the list of supported chips and see if what you want to use it on is supported.

What's your business contact?

Why do you ask?
