I managed to install Win98 on a P45/ICH10 DDR2 board (MSI P45 Neo3-FR) with the retrofitted drivers and a Q9650 CPU. I now want to take it even further, and get a P45/ICH10 DDR3 board and install Win98SE on that machine. Basically to allow more RAM and a parallel Win7/Win10 installation.

I am facing the problem that Win98SE requires max 512MB of RAM when installing. For DDR2 that was not an issue as I got a 256MB module and installed from that. With Patchmem I then managed to use physical 8GB later. Now, with DDR3, there just aren't any modules with less than 1GB so Win98SE won't install.

How can I still install Win98SE on this DDR3 system?

One approach I had in mind is just to use the running Win98SE installation/SSD and plug it into the DDR3 system. The drivers should be the same so it wouldn't cause any hickups. I am correct there?

you can install win98 with a 1gb stick i usually do its only when you go above that you will have problems, if i remember right you should be able to install normally with more ram until the point windows refuses to boot, after POST press F8 then boot to command prompt then install patchmem from there, or you could do as you said and just switch the hdd from your ddr2 system since the boards use the same chipset it should be no problem, i do it all the time even with different boards/chipsets
