Hi, I got a report that old Norton Disk Doctor versions make LBAcache panic. The offending function is int 13.ee (which means "add 1024 to cylinder number for next int 13 call only, similar to int 13.ef which adds CX to cylinder number for next int 13 call only - both take DL as drive number argument and return AH=0 and NoCarry if SWBIOS (func ee) or Drive Rocket (func ef) are installed).
Func ee is supported by HyperDisk and PC Cache, func ef is supported by NOW! cache (according to Ralf Browns Interrupt List). Newer Norton Disk Doctor versions no longer use offending functions (I assume they just use normal LBA int 13 calls instead). Do you know other software which uses those functions? Do you know if OnTrack or EzDrive still support those functions at all? (both are installed "in" the MBR and stay in RAM to supply int 13 functions if you have an old BIOS which does not support those or has bugs, e.g. if your BIOS has a 32 MB bug or lacks LBA support etc.) Should LBAcache support function ee, ef or both? Probably not...
