This laptop can be upgraded up to 200Mhz Socket 7 Intel Pentium CPU. For example i was able to install Intel Pentium SY045 Socket 7 200mhz cpu. There was a problem with cpu frequency, it just run at 100mhz, we need to adjust SW1 switch to the correct frequency. And because the official manual does not describe how to correctly calibrate the clock speed. I've made the table with the every possible configuration, please note that the SW1 switch is located nearby cpu itself.
