usb keyboard / DVD Rom issue

Hi,

I am trying to install RHEL 6.0 Server on Intel J1800 Motherboard but facing following issues during installation :

1) Not Detecting USB Keyboard during installation. USB Keyboard is working till first sceen is displayed ( where various install options is displayed) but stops working in next screen ( Language Selection ). If I connect PS/2 keyboard it is working OK.

2) Not detecting USB DVD ROM. I am installing through external DVD ROM. During installation it is not detecting this Media & asks for Installation Media. I tried to provide various drivers but still it is not accepting. If I install through Internal DVD-ROM ther is no issue.

3) Not detecting USB Keyboard after installation. I have managed to install through PS/2 keyboard & Internal CD ROM, but after installation the USB Keyboard is not detected.

Request you to please provide solution to above issues....
