Install Cache ModuleMay 31, 1999
By David Risley
On many late-486s and early Pentiums, external cache, or Level 2 cache, was installed in a slot. This was later abandoned in favor of on-board cache, which most modern boards have. If you are installing a newer board with on-board cache, you can skip this step.
The cache module is usually called the COASt module. It is not universal. Like RAM, there are different types, and you need to makes sure you are installing the right type.
Follow this simple procedure to install your COASt module, if you have one:
- Line It Up This is pretty easy. COASt modules are keyed to prevent incorrect installation. This is done by placing an indent on some point other than the halfway point, thereby leaving a different amount of contacts on one side of the indent than another.
- Insert The Module Once lined up, push the module into the slot. This may require a bit of pressure, but don't force it. Make sure the motherboard is on a flat surface so that you don't flex the board. Like a card, it may be easier to rock the module, installing one side, then the other.
- Check Your Work You're pretty much done. Just make sure that the contacts are almost all the way into the slot, and that, obviously, the module sticks straight off the motherboard.
