There are Intel overdrive cpus designed for socket 5 which would speed you up anywhere from 125mhz to 180mhz depending on which overdrive you use
So I just checked on the Pentium 100MHz on cpu-world.com and it supports 1.5x (66 MHz FSB) or 2x (50 MHz FSB)
Seeing the dip switch settings on my mobo, it looks like the only option for a Pentium 100 would be 2x (50 MHz FSB) That makes my board look Pentium 100 is the fastest CPU supported on my board, it says so on the PCB. I
--------------------------------
Would an AMD K5 work?
There is no way to set the multiplier to 1.5x on this board. Only 2x/3x and 1x/2x settings are available as pictured. I believe my mobo has the same switch block as Malc does, just no Pentium 120 support.
I see on cpu-world.com that a K6-2 233 with 66 FSB has a multiplier of 3.5x. How does it work at 1.5x?
Thanks for the post, w9gb. I'll see if any of this helps me once I get time to work on the system.Your Jumpers and Switches are Likely Incorrectly Set.
The Gateway P5-120 or Intel Technical Product Summery manuals should resolve.
I assume you have the Baby AT form factor installed in this Computer Case.
APPENDIX B : Page 15 —> Switch 6, ON; (Switch setting for 120 MHz)
Switches 7 and 8 —> CPU External Operating Frequency
Default is 50 MHz (both switches OFF);
For 60 MHz ( SW-7 ON; SW-8 OFF)
For 66 MHz (Switch 7, OFF; Switch 8, ON)
The Gateway 2000 series , P5-120 used the early versions of Intel Advanced/ZP (Zappa) motherboard
without the L2 cache parts installed (Gateway cost reduction and believed, at that time, to not be worth $$).
This Intel motherboard used the 430FX chipset (PCIset FX Triton I)
You likely have this BIOS version: AMI 1.00.03.BS0T : Gateway OEM
Intel Advanced/ZP (Zappa)
Intel Advanced/ZP (Zappa) is a motherboard based on the Intel 430FX (PCIset FX Triton I) chipset. Get specs, BIOS, documentation and more!theretroweb.com
Later BIOS: AMI 1.00.11.BS0T : Gateway hard disk support up to 8.4GB
A MR BIOS version is available

As long as your BIOS doesn't crash during detection, you can use XUB or a DDO (Dynamic Drive Overlay) to work around this limitation in software. Then you can use larger drives without issues.My BIOS can't recognize some 2GB hard drives even! I'm forced to use smaller drives.
