WIFI driver from EasyOS to Raspup?

[sandspur]

Seeking a WIFI driver from another Puppy version to another.

I am running EasyOS on a USB SSD on a Raspberry Pi 400. Its wifi works.

I have Raspup 8.2.1 on a micro SD card but when it is booted up on the RPi 400 it does not 'see' the wifi interface even though when lspci -vnn is run in a terminal it shows a Broadcom device BCM 2711CO.

The big question: Can I get the wifi driver from EasyOS on to the Raspup system? The micro SSD card is visible as SDB when EasOS is running.

If so --- please make suggestions how it might be done.

Drivers are kernel specific and have to be already in the kernel (when it is compiled) or compiled specifically for that kernel.
So you cannot switch them between kernels.

Firmware is also needed and it can be used with any kernel.
The firmware is not in the kernel, but provided with the the OS, as firmware files specific for the hardware.

The all possible firmware software package is very large in size.
So a lot of OS's will provide the firmware that is most likely needed.
So half the OS is not just firmware.
