cp
thanks a zillion for your help and instructions, things work like a charm now.just for other people to know about the solution the following will make the dell 19" wide screen work with a resolution of 1440x900 resolution.
1. install the patch sent by cp - request it if you need it
2. always state your motherboard name and chipset name - mine was asus P4SGX-MX, with a SiS650GX chipset.
3. even after upgrades of bios from esupport.com, the VBIOS version was still 1.10.x which was old.
4. after the upgrade from cp, VBIOS version is now 2.31.x which is the prerequisite for installing the univga drivers available from
www.sis.com
5. last but not least, though sis say one should install univga drivers version 2 for sis650 vga in built graphics card, i installed univga 3, and thats it.
6. reboot once and viola!! you find the 1440x900 resolution.
brilliant cp !!
thanks again
