8739,"Checksum error in BIOS function int 13h, ah=48h (extended get drive parameters) => Fixed in SVN",madanra,,"I've started writing an OS, and noticed that the BIOS function 13h, ah=48h (extended get drive parameters, see http://www.ctyme.com/intr/rb-0715.htm for Ralf Brown's description) appears to give an incorrect checksum. In the description of the function, Ralf Brown says ""checksum of bytes 1Eh-40h (two's complement of sum, which makes the 8-bit sum of bytes 1Eh-41h equal 00h)"". On Bochs and VirtualPC, this is the case, but on VirtualBox the byte sum is FFh.",defect,closed,virtual disk,VirtualBox 4.0.4,fixed,bios drive parameters checksum,,other,other
