Need help to install sco openserver 5

Hi,
Im installing sco openserver 5 (OpenServer-5.0.7Hw-10Jun05_1800.iso) on a vmware server 1.0.4.
Installation is ok but on when x server is loading i just can login, mouse does not move and most of keyboard cases do not respond.
I choose usb mouse + french keyboard while installating, should i chose others options ?.

I m actually trying to install informix, using ssh and winscp.
The other problem is that to install informix, i need to push return case but the return case on keyboard is not recognized...

Could you help me please, i tried too with the last vmware server, same problems.

Thank you
