Hi!

I am currently working on a little IA32 / Real Mode emulator. One problem ist that MS-DOS 6.22 calls operation 0x41 of Interrupt 0x15 during the boot process and I don't find any information regarding that operation.

I verified the call so it isn't a bug in my code by using bochs as well (DOS 6.22 boot process, linear address 0x23E3). Do you have any information about it?

Thanks in advance!

Iirc Ralf Brown's Interrupt list is linked from the wiki, search there next time.

Edit: Oh, and searching for "Int 15 AH=41" on google returns this as the fourth result - http://www.htl-steyr.ac.at/~morg/pcinfo ... te7aeo.htm
