the CMOS battery just died.

all puters this old do that, the battery is good for 7-10 years,
and all fail.
DO NOT FLASH your BIOS, fix the real problem first

when the battery dies, all our bios setting were lost
including boot device, and order
fix battery
then go into BIOS and put back boot order.

I have found that any "burned" discs will not be read on older cd/radio combinations. The newer sets will tell you on the box what formats can be read...I also found this to be true on dvd players

Igi cd not found.please insert cd in drive

You have not told whether you are installing through CD/DVD or online through internet or directly from your HDD. The error media not found means that the required files which your driver setup wants to copy are not accessible to it. If you are installing through internet then the problem is dead hyperlink. try to download from some other site and then install. If you are installing through CD then the problem is with the CD the files written on the CD is corrupted or the CD is scratched. If you are installing through HDD then It is asking for your Operating system CD. Put the CD in the CD tray and it won't give any error.

maybe cd lens is damaged in which case u may need to change the drive itself

first find the cd/dvd of the OS then go to BIOS choose first boot device to (your cd/dvd rom) then put the cd in the cd rom and install itit will solve the problem

your problem is very clear... your cd-rom is corrupted.. install new windows... NOTE-do this only if your cd drive is NOT displayed in my computer..
please vote for me...im sure this will solve your problem...

This is the only site that I found that deals with that brand.

You need to go to the website of whoever made the motherboard and get the BIOS flash utility and the BIOS binary file to update your BIOS. Make sure you get the right one, as using the wrong one can render your motherboard worthless. The BIOS file has to be the exact match. There is no such thing as close in this situation.

The BIOS chip holds information about your motherboard hardware. It is reprogrammable. It uses what is known electrically erasable read only memory. This is also called Flash memory. Reprogramming is called flashing. When you flash the BIOS, all data is erased, then the new data is written. The flash utility will most likely allow you to save the old contents, but you might have an extremely tough time recovering from an improper flash. You'll also probably need a couple of floppy disks, one of which may have to be bootable. If you need a bootable floppy disk, you can get an image file from http://www.bootdisk.com.

any digital audio cd-r will work. i found that maxell digital audio cd-r's work the best. you can pick them up a 20 pack for around $15
