i have no problem from the message but when windows is started , it says no ps/2 mouse present . since day before yesterday when i start my computer i get a message at the started screen which is "update escd successfully ".We use data about you for a number of purposes explained in the links below.By continuing to browse our site you agree to our use of data and cookies.Take a paper clip and stick it into the holes in the header connector to determine which lead needs to go to what pin on the DB25 using your multimeter. You then need to get a 5V line from another computer (The Red wire on a molex connector).Solder three diodes in series and connect them to the 5V line.
So I retry, now it won't even try to write the bios. The motherboard is supposed to have a built in bios recovery mode, but it seems that was wiped out as well by the Windows flash utility.I then wired this to the ribbon cable and hooked the power connector into another running machine. HOWTO: Supplies: To make the cable I used a DB25M TO IDC10 SERIAL connector. They look like this: The header is found on the motherboard directly to the left of the south bridge.Here is how the header pins are numbered: Here is a table showing which header pins should be connected to what parallel pins. Here's what my cable looks like (Note: it looks like the power lead is connected to the DB25 but in fact it is solder to the ribbon, it goes to pin 1 on the header) If you use a cable similar to mine, open it up and desolder the ribbon from the connector.I made a really bad attempt at using a chopped up parallel cable and the ends from a USB header port thing.This didn't work out well so I found at the local electronics store a parallel connector with a ribbon cable on it.
