I am getting an Invalid Return from my DPMI at address 0037:0168 when ever I try to install Win 98. I am using the following hardware:

Pentium 166 Mhz CPU
16 MB EDO RAM
1.6 gig Western Digital HD
1 Meg Cirrus Logic Video PCI 5430
2x Mitsumi CD-ROM
Yamaha OPL-3D Sound Card

I can not finish the install process on this machine. What process is causing this and what should I do to fix it. Thank You in advance for any help you may be able to provide.
