IBM ThinkPad 600 - Modem Problems

Modem Problems
Problem Action
The internal modem does
not work when you boot
your computer from an
operating system other
than Windows 95.
The operating system may be sharing the same IRQ levels as your modem.
The ThinkPad modem software might not work under these conditions. You
must cancel the IRQ shared condition to use the modem.
Refer to Chapter 6, “Resolving System Resource Conflicts” on page 83 to
cancel the IRQ shared condition.
