Solution:

Please be informed that, due to incompatibility problem with AMD and Cyrix CPU, the first lot of PCA-6154-00A1 x 250 pcs and PCA-6154L-00A1 x 150 pcs are not suggested to use Cyrix M2 200 MHz or above and AMD K6 200 MHz or above CPU. ( But It is O.K. to use Intel up to 233 MHz, AMD and Cyrix below 200 MHz) There will be one page of User's Note in the User's manual of PCA-6154/L to explain this to the end users. However,the incompatibility problem is only happened to this 400 pcs mentioned above. From the next production of PCA-6154/L after the 400 pcs( Revision will be PCA-6154/L-00A2) will support all Pentium CPU ( Intel, AMD, Cyrix and IDT up to 233 MHz) .
