ReactOS-0.4.15-release-1-x86.iso

Got it to install on Promxox 9.2.
PowerEdge R230 ... CPU(s) 8 x Intel(R) Xeon(R) CPU E3-1270 v6 @ 3.80GHz

It's 32-bit.
It wouldn't install until I used these settings. (only) 1cpu. (only) 2gb. IDE drive. SeaBIOS. i440fx machine.
It did boot. Failed to install device drivers. It did get online. Hehehe. Floppy disks controllers. Wine Internet Explorer.

Installed LZDoom/Freedoom using Applications Manager. It ran.

I don't know. The OS runs. Interesting.
