Hi Bill,
group. The short version: With the coming of Wayland I have little choice but to get new display adapters for all of my Linux machines.
You probably are not technically forced to use Wayland: Most distros give you a choice of drivers to pick from, even when they recommend one specific framework as default.
My FreeDOS system is hosted on an old mainboard - an Asus P5A-B. This board does not have USB ports and does not have emulation support
That is a Socket 7 board with EDO/SDRAM DIMM, AGP, PCI and ISA. Are you sure that you need a board THAT old for your DOS tasks? According to https://www.anandtech.com/show/116 P5A-B should have two USB ports. Maybe you just need a slot bracket to access them. If that fails, you can still use a PCI USB adapter card. I agree Bad or missing USB legacy support in the BIOS may be an issue, but:
I could install a board with USB ports, but that does not help FreeDOS.
Without BIOS support, try DOS USB drivers. I guess it would be acceptable to have to connect a PS/2 keyboard directly, without a KVM switch, for BIOS setup purposes once, as long as DOS can use the USB keyboard properly after booting with USB drivers loaded.
The Raspberry Pi Pico is not a full-on Pi. It is a microcontroller much like an Arduino, though with quite a bit more processing power.
Good to know. I checked what "USB PS/2 Arduino" brings up, so in case somebody else is curious about alternatives: - Stackexchange says flexible USB keyboards can do PS/2 data and clock on USB D- and D+ respectively, and of course +5V and GND, so that is the wiring which your USB KVM switch MIGHT support: https://arduino.stackexchange.com/questions/54853/how-to-convert-usb-to-ps-2 https://i.stack.imgur.com/tXhcw.jpg - Instructables has an Arduino PS/2 to USB adapter project, but that is for connecting PS/2 keyboards to modern computers. - There are Arduino libraries to use PS/2 keyboard or mouse, so that again is easier than the other way round, simulating them. - Arduinos default to showing up as serial port devices when you plug them via USB, but there are versatile libraries like V-USB: https://www.obdev.at/products/vusb/index.html My quick search did not bring up a ready-made solution for what you were looking for, I just THINK it should be possible with much less computing power even than an Arduino style RPi Pico.
At $4 a Pico is also cheaper than most Arduinos.
