I recently bought a latitude cpx h500gt with default bios v08, as i was surfing the dell forum a couple of weeks ago i came to the point wherein i need to upgrade my bios to v13 inorder to accept 40 to 137 gig of hard drive. i upgraded my bios to v13 and the problem starts coming.

i experienced a bad behavior with the mouse starts jumping and automatically right clicks. i reverted to bios v08 now the touchpad starts to misbehave but using the external mouse is doing great. im using windows 98 right now.

Thanks everyone!!!!
