Have a nice Dell 5150 that I had put Windows 7 on and had running pretty decent, realized that the chipset on it is an 850PM, so I thought hey what the heck, lets see if I can get 98SE on there and running good.

General hardware:
P4 3.06Ghz
Intel 850PM chipset
Sigmatel 9750 audio
Nvidia 5200FX (32mb)
Broadcom 440x ethernet
Broadcom BCM94306MP Wireless card
512mb ddr1 333mhz
40gb Fujitsu HD
Quanta SBW-242 optical DVD/CD-rw drive

Here's the problem, I can get an image onto the drive (image of Dell D600) and upon first boot it detected lots of hardware, lots of reboots, it gets to desktop and appears to function fine, however there are some problems, the biggest one being that it does not detect the optical drive. I tried installing Intel 6.3.0.1007 chipset package and it loaded drivers for some things like usb controllers & such but did not fix the issue of not seeing the optical drive. (Which works just fine to boot from BIOS or in any other OS, etc. Also I tried a clean install but it couldn't finish because at some point it can't see the optical drive and continue the install after it reboots, wants files from the cd to continue but can't see the drive to use. I did this on a separate hard drive and then popped back in the original that I imaged when it did not work.)

Under DM, I have under hard disk controllers;
Intel 82801DBM Ultra ATA Storage Controller - 24CA - looks fine no exclamation.
Primary IDE Controller (dual fifo) - this has yellow exclamation, says device is either not working properly, not present or does not have all drivers installed. Does not say it has any resource conflicts.
Secondary IDE Controller (dual fifo) - looks fine, no exclamation.

It seems that this issue crops up on laptops / notebooks as I was trying to research a fix, others seem to have had variations of this problem as well, but found no real fixes for it. And so before I give up on it, I come here.
