Is there an interrupt to get the BIOS serial number as shown on the power-up screen? --------------------------------------------- Q1: Is there an interrupt to get the BIOS serial number as shown on the power-up screen? A: (Ralf Brown) There is no general way to get the serial number. In most cases, you need to know the proper offset in the BIOS image for that particular make, model, and revision of the BIOS (and that offset may not even be present in the real-mode image loaded into shadow RAM!). Further, with a flashable BIOS, it is quite likely that every single machine that has been updated with a downloadable upgrade from the Web will have identical serial numbers, assuming they weren't already identical as shipped from the factory with the original BIOS version. Because of this, the BIOS serial number is essentially useless for any identification purposes. --------------------------------------------- End of File
