Looking at the system board, you will find an Accelerated Graphics Port slot. Inserted within the slot is a port block adapter, which will not allow for any AGP video adapter to be installed into the slot without being removed. When this blocking adapter is removed, and any AGP video adapter installed, the adapter will not function and the BIOS may not see the adapter.
ThinkCentre (type 2296, 8191, 8198, 8199, 8316, 8434) and NetVista (type 8181, 8182, 8303, 8304, 8306, 8308, 8310, 8311, 8312, 8313, 8314, 8315, 2289, 6824) systems configured with one of the following system boards with an AGP port block adapter:
- IBM FRU 02R4637
- IBM FRU 88P8477
- IBM FRU 49P1605, replaced by 02R4087
None. No hardware should by replaced for the above symptom. The system is working as designed. This is a limitation of the system board as these are listed as Economy or Value systems with the functionality of the Intel 845GL chipset.
