|Will a pci wifi card work with an older computer? |
Yes, if it has drivers for the operating system on the older PC. So, check to ensure you have, or can download, Windows 98 drivers for the PCI device you wish to plug into the computer. If you can't find 98 drivers, it won't work.
As to other devices, the same applies.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
