Customer Review

As others have mentioned, finding software can be tricky. I did manage to track it down: Prepare to spend another 10 bucks.

SkyGZ maintains software and sells his own version of this programmer on taobao, as well as a more advanced programmer that can also handle 1.8V and 2.5V. He will sell you his software, which works with this piece of hardware. The current software version (as of April 2017) for this programmer is 1.31; the Youtube link in the other comment has an older 1.18, before SkyGZ started using copy protection.

Save yourself a lengthy search and scary download links with virus warnings, spend another 10 bucks on the software. Keep in mind SkyGZ is in China, that's 12 hours from US east coast and 9 hours from US west coast, if I have my timezone math roughly right. My 9pm is his 9am.

To get the software:
- Send an email to skygz@qq.com , telling him you'd like to buy the software only for the CH341A programmer.
- He'll respond and give you a paypal link for sending him 10 bucks. He'll also instruct you to give him a yahoo.com email address (I guess gmail kills ZIP files with EXE files in them), and warns you that if you pirate his software, he'll blacklist you.
- Once you've paid the man - in my case, some 9 hours later, that timezone gap - he'll send you an email with a ZIP attachment. Inside is the software, personalized to you.
- Run the CH341A.EXE, it'll pop up a registration screen. Email the username and hardware ID it him, he'll send you back an .XML file which you "Import" on that screen.
- And that's it, you have your very own personalized copy of CH341A, with lifetime version upgrades!

The ZIP he sends also has the parallel/I2C and serial driver files. My understanding is you want to keep the jumper on "parallel", insert the device in USB, then install the parallel driver. That'll have you all set for programming a BIOS chip.

If you ever change motherboard / computers, he'll reissue a license to you "as long as you don't get annoying with it." I guess that means a believable rate of PC change is fine.

The man writes a blog as well, but Amazon frowns on a direct link to it.
