have you tried this on a pci-e ide adapter yet?
i want one of these for my old 486
but also just went “gee it would be nice to just scroll a menu and select different usb LiveCDs for a lab box” and not constantly switching or losing usb dongles for them
ive done boot loader menus and sooner or later one OS clobbers or screws up the others. so im into the idea of segregating them and using your device to select imgs.
yeah its something i could solve with a PXE environment but then i have external dependencies that change over the years as im moving around and getting different internet providers, home equipment , or using different solutions for dhcp and routing etc. this would work well on an airgapped system even if its been collecting dust on a shelf for a few years
