Abstract
A method of obtaining the BIOS version date in the windows operating system using dynamic virtual device drivers (VxDs). First, input and output parameter buffers are defined and the initial address and area size of search memory are obtained. The physical address is mapped to a linear address. After initializing the address shift, the system makes sure the shift is smaller than the memory size minus 8. The system then checks that the address pointed by the initial address plus the shift contains a number. The address of the number is taken as the base address. The values in the zeroth through the ninth bytes of the base address are preserved and returned to the application routine, giving the BIOS version date.
