In order to process your order

In order to send you the correct Uboot chip, We need to know the base clock of your board.

On some versions of U-Boot you can see the base clock in the System Information U-Boot menu (CLK freq).

If your Uboot doesn't display the CLK frequency, please run this AmigaOS4.1 'check_460_baseclock' utility.

You need to set the ‘E’ protection bit on the file, and then run it from a shell. It will report the CLK freq.

Give us your base clock so that we can send the correct chip to you.

Thank you.

About the installation

Note that you will have to remove the chip from its socket. The better solution would be to use such tool:

Extracting tool

Alternatively, you can use a paperclip bent on one end. It may not be as easy as the tool, but it can work.
