The ReactOS website is pretty handy for drivers - see this page. It can be handy for exactly this kind of thing. Note: I strongly recommend installing ReactOS alongside a second operating system, probably a Linux would be best.
REACTOS LIVE CD INSTALL
The FreeDOS install media includes a packet driver for the Intel PRO/100+ NIC on the E500, so I could get online from FreeDOS but not ReactOS! Because ReactOS mounted the FreeDOS partition as D:, I booted into FreeDOS, set up the network and used Lynx (or Links or Dillo) to download any drivers I needed, and then when I booted ReactOS I just copied them off the FreeDOS partition. Once that was done, I could boot into ReactOS. This meant I could not boot ReactOS, but that’s OK, because I then did an install of SliTaz to set up GRUB2 to boot ReactOS, FreeDOS and SliTaz.


Installed the bootloader to the partition not the MBR. I used a SliTaz live disc to set up the partition structure and then booted from the ReactOS CD and stepped through, choosing the correct partition and doing a full format of the C. Installed on a 30 GB partition (sda2 in Linux-speak) on a Compaq E500 (Pentium III, 384 MB RAM, dates from around 2002 or something.)
