A2386 with TI 486SLC2-50 - only shows 25Mhz and no cache enabled
Hello Amigans!
This weekend's project is an A2386 Bridgeboard. I have it working well inside my A2000 with WB 2.1 and 25Mhz A2630. It has the clock doubled 486SLC2 chip installed. I have a heatsink and fan on it to keep it cool. It has been running perfectly all day. I am able to do a lot, I installed DOS 6.22 via shared HD Amiga floppy, played a VGA game and ran a few utilities though I have not installed an IDE HDD on the ISA bus just yet. (Using slow hardfile for now) I researched several forums about the clock doubled TI486SXLC2-G50-PQ CPU and my big question is how to enable 50Mhz speed and also enable the cache? I downloaded BBCPUCLK from Aminet and put the execute statement inside my autoexec.bat and I know it runs without error on reboot. Launching Norton sysinfo (v8) still shows a 25Mhz clock and a score of only 15.7 I remember finding a utility searching Vogon's or somewhere, specific to the TI chip for enabling clock doubling and the 8k cache. I imagine I need this exact TI utility to enable the goodies. I see references to it on other forums, but I cannot locate the software. Can anyone help me? I am hoping to get the CPU set correctly, then tackle IDE HDD next. Cheers, Tim |

Run "CACHE486.EXE 2+" in autoexec.bat

Replied on AmiBay as well. Almost there. I'm at 39.4 Norton SI, so I assume clock double is not on, or is this the max?
Thanks @nobodyii |

SOLVED. Missed the "2+" part in my autoexec.
