QNX on a Laptop

Post by Gabriel Coindreau » Sat Apr 26, 2003 9:42 pm

So far I have succeded running QNX2 (2.21atp) on quite modern laptops by
disabling the cache of the CPU using the BIOS, installing the QNX2 OS on a
partition on the hard disk and then enabling the cache again. Another
limitation is to have an integrated floppy drive (asking QNX2 to boot using
an USB drive would be a little extreme)

It had worked on several laptops over the years all the way to a Toshiba
4300 Satellite Pro (Pentium 3 - 700MHz) which I am currently using. I have
three disk partitions, one with QNX2, one with QNX4 and one with Windows98.

I need to change my laptop to a more powerful system, I have tried an IBM
Thinkpad A31 (Pentium 4 - 1.9GHz) with no success; problem is that the IBM
BIOS doesn't lets you remove the CPU cache.

Is anyone out there running QNX2 on a modern laptop? What laptop model are
you using?

Regards

Gabriel,
The unfortunate thing is that for us who would like to customize
laptops we are restricted in this respect. Buy a new laptop with Windows,
or else. :) Anyway, Dell laptops and computers have an option for "CPU
Information" and changing the speed from "Normal" to "Compatible" which
will allow you to run QNX (but try Linux instead...;) )
