I have a 10 y.o. Gateway G6-400 PC with an Intel Tabor II motherboard and a PII 400 Mhz processor. I have a salvaged PIII processor I am hoping to use as an upgrade. The Gateway specs page does link to "Pentium III processor serial number Q and A" in the FAQ section of the motherboards specs at
Gateway Support - 4000446*Intel (Tabor 2) BX Motherboard w/ Integrated Audio R2
but it does not specifically say that this motherboard will accept the PIII. FWIW, I have 320 MB RAM
Neither Gateway nor Intel would field questions...
I wish to find out if the power supply, Tabor II motherboard and 16MB Ensoniq AGP Graphics Accelerator / video card are compatible with the PIII processor.
