QNX boot on 20 GB hard drive

Hi,

I have just installed the March 2001 CD on a 20 GB hard drive.

After the install, looking at the partition with fdisk, it shows that
cylinder 0-2430 are used for QNX 4 partition. The boot shows maybe.

The system seems to be working and it boots okay. Should I change anything
or is this okay?

Do I need to change the BIOS to LBA and re-install QNX 4? Does LBA affect
performance?

Or do I need to create two partitions, one for booting QNX 4 and one for
whatever?

I wish to have a simple 1 partition solution, or something that will look
very similar.

What’s the best way (recommended way) of doing this?

TIA

Augie
