Modern server workstations equipped with updated peripherals and cards
Looking at the era we’re entering, modern expansion cards and peripherals seem capable of backward compatibility with standards such as PCI-X or general PCI. It appears they can connect without needing a middle device to link the peripheral to the motherboard.
It seems you're unsure about the compatibility of PCI-E devices with a motherboard that only supports PCI-X. Are you referring to connecting a PCI-E card into a PCI-X slot, or is it about using a PCI-X/PCI card on a new PCI-E motherboard? Either way, the answer is no.
I believed Legacy PCI remains on boards. https://www.asus.com/us/Motherboards/PRIME-X370-A/ PCI-X vanished when PCI was introduced. PCI is disappearing from PCI-E 1x
I wanted to find out if it's possible to install a PCI-e device in a PCI slot.
I need to understand the specific hardware you're referring to. If you mean by PCI-E... it's been available for a while. At least socket A (462 pin AMD) but didn't support PCI-X, which was replaced by PCI and later PCI-E. Nowadays, a PCI video card should fit in any motherboard with the slot. Actual performance in the OS depends on available drivers. This could be a problem if you're using a modern motherboard but trying to run Windows XP, as support would likely be lacking. So the answer is both yes and no at once.
Additionally, several contemporary graphics cards need UEFI BIOS support; lacking it can cause compatibility problems.
