Installing RH 7 neighbour table overflow

I have IBM Pcserver 320, with 133 Mhz Dual CPU, Adaptech series SCSI card, 4.3 GB Hdd, 128 MB IBM EDO Ram.

I am installing Redhat 7.0 but while POST INSTALLATION my pc stops responding
( Pressing Ctrl+Alt+F4) it shows message of
“<4> neighbour table overflow ”

It is not hanging, mouse, keyboard works but no disk activity, and status bar of POST installation do not go ahead.

Please Help me out…
