mode).
Intel 486DX, 486SX, 486DX2, 486SX2, 486DX4,
or AMD using write-through caching,

mode).
Setting Jumpers for AMD Plus CPU Caching Modes for L1 Cache Memory
The caching mode for the L1 cache memory for AMD CPUs is included in the CPU number. CPUs that support write-back caching have
B
as
the last letter. CPUs that support write-through caching have
T
as the last letter. J9 and J12 should be set as follows for AMD CPUs:
