What is your purpose in adding a second ISA slot? If in order to use multiple ISA devices, why not try this. Short on ISA slots? Try this.

I fixed it by replacing the CPU socket and now everything is fine. Need help replacing the pins of the Socket3 socket I get the impression that the CPU socket contacts are not in good contact due to rust, which makes it look normal under DX2-66 because of the 5V voltage and lower data transfer speed …

I managed to fix it. Step 1: I carefully removed the Socket3 socket with a heat gun from a EXP4044 that had been scrapped due to a leaking battery, and I could see that it had perfect contacts. 好插座.jpg Step 2: Similarly, carefully removing the CPU socket on the HIPPO-15 with a heat gun, and then I …

Loosen your memory timings... Set both memory and cache timings to the lowest setting possible. If the freezing goes away, then the issue is that your timings are too tight. Thank you for your answer, I have a question, The 486DX2-66 and X5-133 use the same 33MHz FSB, do they need to have different …

Terrible, for what purpose would it be done? I purchased a HIPPO 15 Rev 1.23 motherboard today, which is expected to arrive on January 2nd, I can help you identify the specifications of the missing capacitors, you need to be patient.
