I have modified the BIOS to integrate an RTC into port 70h.

From the same Micro8088 or NuXT we can use the Sergey xiflash.exe application that I modified so that it does not hang during recording:

With the following parameters:

xiflash -p -i BIOS097b.BIN

I have made a pull request in Sergey's repository:

https://github.com/skiselev/8088_bios/pull/2

Is beta but while it is reviewed, validated and optimized by Sergey you can use it and report problems, if any.

If you have an RTC card like the one designed by SMBacker, for example, be sure to configure it for access on port 70h.
