Could you help me? The following program (Borland C 3.1) works incorrectly on one suspicious computer only: main(void) { ... setvect(8,Timer); // store to interrupt routine ... } void interrupt Timer(void) { ... outport(0x20,0x20); // enable interrupt (work incorrectly) } On the other computers the program works correctly. The suspicious computer parameters: 486DX4 AMIBIOS 1994. Include PCI and ISA bus, PCI VGA and MS DOS 6.22. Other orograms runs on this computer correctly. Questions: 1. Is the statement (enable interrupt) "outport(0x20,0x20)" correct ? 2. How to solve a such problem ? Thanks Karel Sent via Deja.com http://www.deja.com/ Before you buy.
