I specified a format buffer for one trak and called intr 13h with ah=17h before. This interrupt should set the disc type: Set al=3 for 1.2MB disc in 1.2MB drive. On interrupt ah=5 it seems to be neccessary to set al=1 for one trak. It seems to work, but when writing it brings errors ah=4 on sector 17, i also don't understand this. Perhaps we should exchange our routines to see if any of us solves a part of the problem. Please answer on notes. Franz Dreismann email:franz@hpugrca.rtg.hp.com
