DIVT - Display the interrupt vector table

Description

Mr. Avery Lee once told us that his software VGAPaint 386 has a BIG bug, because it does not restore some interrupt vectors on exit correctly.

We found it very painful to use DOS' DEBUG for monitoring the interrupt vector table. So we wrote DIVT to make life a little easier.

DIVT directly reads the interrupt vector table at memory address 0:0 and displays each entry in the following way:

  Int 00h: 0139:108A
  Int 01h: 0070:06F4
  Int 02h: F000:E2C3
  .
  .
  .
  Int FEh: 0201:0008
  Int FFh: FF00:292C

System requirements

• Intel i8086/88 microprocessor (or compatibles)
• Microsoft MS-DOS 1.0 (or compatibles)
