I got a laptop:
- Intel C2D L7500
- Intel 965 graphics
- 1024 Gb RAM
- 120 Gb HDD (SATA AHCI)
- WinXP SP3
- VmWare Workstation 6.0.0
- NO floppy
- CD drive (on Primary IDE channel)

In VmWare, I created a virtual HDD 1 Gb and reserved 64 Mb RAM for QNX 4.24.
For QNX, in the hardware options I selected only display, virtual HDD, memory & one processor.

After completion of scanning the hardware, setup program displays a popup "Please insert the QNX Install CD into the CD 
Rom Drive".
According to "QNX RTOS 4 Knowledge Base" (http://www.qnx.com/developers/qnx4/qnx4kb/solution.html?code=9512):
-----------------------------------------------------
This is a bug with the installer where the Fsys.* drivers have problems with the CD-ROM drive being on the secondary IDE
 channel, or on a SCSI chain and mounted improperly.
-----------------------------------------------------
First, my CD drive was on primary channel.
But anyway, I tried all possible combinations for HDD & CD:
HDD - IDE 0.0, CD - IDE 0.1
HDD - IDE 0.1, CD - IDE 0.0
HDD - IDE 1.0, CD - IDE 1.1
HDD - IDE 1.1, CD - IDE 1.0
But it did not help.
