I would reccomend that you user vesa driver in place of cyrix above. It gives me a resolution of 800x600 with 16bit colors with exactly same kind of hardware that you have. But as far locking up of monitor is concerned it still continues but not very often. Probabaly something to do with the memory being shared with the RAM or a bad driver.
