Somehow using a data-based USB stick would nullify having a mouse/keyboard via USB in the installation. However, from personal experience, this only really worked when installing Window 7 from a CD, never from a USB stick. After a couple of weeks when motherboard manufacturers started rolling out BIOS/EFI updates to each of their products and enabling the option allowed users to have a keyboard during a standard install.
With Intel on the Z170 series and above, it was a case of the USB 2.0 needing to be emulated through a BIOS option in order to install Windows 7, due to the EHCI support being removed.
The problems facing users wishing to install Windows 7 who do not have a PS/2 port or peripherals come in two forms: Problem 1: Installing Windows 7 These are most likely to be natively supported over USB 3.0 which can require chipset drivers.) (As a general rule, always use USB 2.0 ports.
Unfortunately, the latter requires a default driver to be able to do this. This results in different levels of engagement: the PS/2 keyboard injects its commands, but this means limited n-key rollover support, whereas a USB keyboard will bundle its commands up and send it over when the system requests it. PS/2 uses interrupts through the system, compared to USB which is based on polling. The main reason why PS/2 should work where USB doesn’t is due to the protocol. However, PS/2 as a connectivity standard is near dead (sometimes new keyboards will offer dual connectivity, like one of my Rosewill mechanical keyboards), with fewer motherboards supporting it, and it falls to USB as a backup. I’ve never known an installation to fail to recognize a PS/2 peripheral, so this is often the best bet. General Solution: Use a PS/2 Keyboard, if the motherboard has a PS/2 portīy default, on most systems, the way to guarantee the presence of a mouse pointer or keyboard activity during installation is to hook up a PS/2 keyboard. This is the primary process that fails on both platforms and acts as a barrier to installation.
When the CD or USB stick is being used to install the OS, the image needs USB drivers in order to activate a mouse or keyboard to navigate the install menus. However, from the 100-series chipsets on Intel and the AM4 motherboards on AMD, this can be an issue. When there’s a mouse/keyboard plugged in, everything else after that is typically simple to configure (installing drivers, etc). The Main Issue: USB Supportįor installing Windows 7, the issues typically revolve around USB support. There may also be other methods to install an unsupported OS, however here are a few solutions. AMD's formal position on Windows 7 on Ryzen is that it is unsupported, and as a result this means they will not provide support around it. Official support refers to driver updates and perhaps security updates, but there’s nothing to stop you trying to install an OS to either system or platform.įor clarification, we did not converse with AMD in writing this piece. 'Official' is a general term: some special customers may receive extended lifetime support, or drivers currently out in the ecosystem still work on the platforms. Given that Microsoft has essentially ended support for the OS, this is the type of response we expect from AMD – Intel has also stopped officially supporting Windows 7 on the newest platforms as well. Which basically translates to "in /boot/boot.Officially, AMD does not support Ryzen CPUs on Windows 7. Mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr I have seen that script online, but it is not the same as on the most recent version of the Cubietruck Vanilla image.īut I managed to find what I was looking for: If I had that answer it would already be in the script.
I can answer to any "why" from the script but I can't tell you how to boot vanilla kernel with help from NAND. What you are trying to accomplish is more complex than understanding this.
