It's unlikely that you even need to change any of the dip switches. These should be set correctly from factory depending on the CPU used.

Since the CPU was factory-installed, leave the dip switches as they are. They are correct already!

Okay, I see. So I want to use 4x for a total speed of 133mhz on 33mhz bus. and 3x for a total speed of 75mhz on a 25mhz bus. Now, Should I use "Pass through" or "Write through? ( this setting is for my motherboard cache right ? ).

Okay, I see. Should I use "Pass through" or "Write through? ( this setting is for my motherboard cache right ? ). No, I think this refers to the L1. As most upgrade devices, it sets the L1 in WT mode for compatibility. However, in this case this is also possible to force the WB mode, in case the …

The write-back settings are listed in the second page linked by Brickpad : https://web.archive.org/web/19980703090959/ht … ddsettings.html I have no idea of what pass-through mean.

As most upgrade devices, it sets the L1 in WT mode for compatibility. However, in this case this is also possible to force the WB mode, in case the BIOS would support it. The L1 cache is inside the CPU. The rest of the system won't care or even notice whether it's WT or WB. This is a combination of …

This CPU should work with most 486 motherboards right? Even though it is a 169-pin CPU it will still fit in most 168-pin sockets and pin #169 should not matter if it is connected or not. The CPU should still operate right ? Wether in an Overdrive socket to standard 168-pin 486 socket. Almost all 486 …
