Lines: 12 Any body has DOS 4.xx complete BPB (Bios Parameter Block) definition? (especiall from offset 0F to offset 1B) I knew of some of the definition (from offset 0 to offset 0F). I think that 4.01 has 1C (hex) byte of BPB, but I do not know the definition. Thanks SteveL stevel%hpdslq@ce.hp.com stevel@hpdslq.HP.com
