I am having problems installing sco unix openserver 5 on a pentium 4 duo core machine. the system has both SATA 200gb hard drive and IDE 40gb hard disk.

I am using a bootable floppy to start the sco unix installation, i am not typing any command line at the boot prompt. when it displays all the hardware configuration it gives me an warning "no root disk controller found", the installation starts with a blue screen after the registration process it gives me an error "notice ram: no ram disk space 1/30" and the installations stops at this point. I dont know what btld to download and the command line to install the driver(if required).

Please help me!!!!
