You need two formatted 1.44MB 3.5" floppy disks.

Prepare the first disk:
- Use the install utitity from the freeldr module to copy the fat bootcode
onto the disk (run 'install fat a:').
- Copy freeldr\obj\i386\setupldr.sys to a:\freeldr.sys.
- Copy ntoskrnl\ntoskrnl.exe to a:\
- Copy hal\halx86\hal.dll to a:\
- Copy bootdata\txtsetup.sif to a:\
- Done.

Prepare the second disk:
- Create directory 'system32'.
- Copy lib\ntdll\ntdll.dll a:\system32
- Copy subsys\system\usetup\usetup.exe to a:\system32\smss.exe
- Copy media\nls\c_1252.nls to a:\
- Copy media\nls\c_347.nls to a:\
- Copy media\nls\l_intl.nls to a:\
- Copy bootdata\txtsetup.sif to a:\
- Copy drivers\dd\blue\blue.sys to a:\
- Copy drivers\dd\floppy\floppy.sys to a:\
- Copy drivers\dd\input\keyboard\keyboard.sys to a:\
- Copy drivers\fs\vfat\vfatfs.sys to a:\
- Copy drivers\storage\atapi\atapi.sys to a:\
- Copy drivers\storage\class2\class2.sys to a:\
- Copy drivers\storage\disk\disk.sys to a:\
- Copy drivers\storage\scsiport\scsiport.sys to a:\
- Done.

Boot ReactOS from the first disk and insert the second one upon request.
ReactOS starts the setup utility but is unable to install. It is only a
proof-of-concept.

Btw, ReactOS boots on my old 486DX-2/75 (28MB RAM) laptop from1995.
