Installed Windows ME via CF to IDE mobo. Afterwards, it was tested and installed with Windows 98 SE with a Fujitsu IDE HDD. One cap changed due to signs of failure (bulging). Board was cleaned with an ultrasonic cleaner prior to testing. Please note this board does not come with slot 1 holder screws / anchors (it does include the slot 1 brackets however) and includes only the motherboard (no I/O shield, cards, etc)
