ROM Types
It is important to use the correct type of BIOS upgrade because, allegedly, the Intel and SST Flash ROMs store the "ESCD" data (which is used to store plug and play data) at different addresses. It is therefore also important that jumper JP13 is set appropriately for your ROM type. If you flash with the wrong BIOS, it'll probably still work but your computer will have Plug and Play problems. Mine, for instance, kept forgetting the PS/2 mouse and serial ports existed and I would have to power off and unplug the mouse before it would re-detect them.
