My original connection to PIN2 for +5V and PIN4 for GND does not work. But still no BIOS access - JP2=ONįor PS/2 to work I have to connect to PIN1 for +5V and PIN3 for GND. I am sure both keyboard are functioning as it react to CAPLOCK, NUM LOCK,CTRL-ALT-DEL after at PXE Boot. In fact if you dont need pin 9 (option 5v) you could use an old male to male serial cable. The equipment at either end always has a female connector, and theyre all wired the same way. Opensrv, could you post your keyboard (V) and (mA) rating at the back of your keyboard which worked?Ĭharles, may be you could share with us which PIN is PS/2 Keyboard is connected to on CN2 (EX490 it's labeled as CN9) block? Have a feeling that the motherboard could not detect the keyboard present even though it is working?īoth PS2 Keyboard, function but could not get access to BIOS (doesn't have "Press DEL to enter setup") Yes, all VGA cables are wired 1-to-1, whether they are regular male-male cables or the relatively rarer male-female extension cables. Mine didn't either until I plugged in the PS/2 keyboard. I am working to resolve the issue and if anyone wants to jump in, please feel free to do so. Thank you to everyone helping (both on the forums and via email). If you are one of those cutomers that could not get the PS2 keyboard to work, can you post (or email me) your bootup screen? Specifically, I would like to see BIOS vendor and version number. A VGA cable carries analog components RGBHV video signal (Red, Green, Blue, Horizontal sync, Vertical Sync) and DDC data. It’s a three row 15 pin connector comes with a screw type locking mechanism. I have one customer who claims his BIOS is newer than the BIOS pictures posted here by mitch672. Brief Description VGA is a popular display standard, stands for Video Graphics Array. Also, if possible, can you provide pictures of the POST screen showing the BIOS vendor and version number. Specifically, about 70% of people claim it's working while %30 claim a problem with the PS2 lines.Ĭan those who got it working post pictures of their setup? I would like to see exactly how you installed your cable adapter (for example, is it inside the computer chassis or outside). Mitch672 bought a cable from me and although his cable is working fine, I am troubled seeing a small number of customers expressing concerns about the PS2 lines not working.
