PS2 ports dead(?) Stuck on POST screen
I've got this socket A mobo which seems to work fine except the PS2 ports
seem to be dead (or at least the kb one isn't responding). No lights flash on the kb when I switch on, but I know the kb is 100% in itself. Problem is also that I've reset the CMOS before using the mobo for the first time and now I can't get past the POST screen cos it says (from memory) CPU unworkable (or similar). I need to get into the BIOS, but I can't without a KB! I've tried a PS2 kb using a ps2 to USB connector, but the BIOS clearly isn't setup to read from a USB kb. Any ideas on how I can get past the POST screen? Any Win98 (SE only?) or XP installation would surely let me use a USB kb, it's just getting past the POST screen that's stopping me! |

Although you wrote that the keyboard is tested working, is it possible it's odd, non-standard in some way? Is it known to be capable of operation with a USB adapter? Generally speaking any semi-moden system will allow use of a USB keyboard to enter the BIOS, just not AFTER the BIOS unless legacy support is enabled. Do you have the opportunity to test the PS/2 port's power? By that I mean taking a voltage meter and/or continuity meter and checking for 5V, making sure that port's fuse isn't blown. You didn't mention the specific motherboard. A link wouldn't hurt either if you have one handy. Are you 100% sure the motherboard supports the processor, including the BIOS version? That wouldn't explain why the keyboard lights aren't coming on, but I've seen some odd keyboard problems in the past with systems that didn't support newer CPUs, yet the board still made a valiant attempt at POSTing, just locked ups or other oddities during POST.

Generally speaking any semi-moden system will allow use of a USB keyboard to enter the BIOS, just not AFTER the BIOS unless legacy support is enabled.

I got this with a Duron 750 and have also tested with an Athlon 900, both of which should work on ANY socket A board. The kb is the one I use for testing all boards I get, but I've tried another with no joy. Dave |

Either way there is clearly no power going to the kb (or an alternative kb I tried). I've also tried plugging the kb into the mouse ps2 to see if the LEDs flashed, but nothing. I have a wireless mouse (see my other reply) and I could try plugging that in to see if it's LED comes on. -- Free Windows/PC help, http://www.geocities.com/sheppola/trouble.html It's a G not a J in gmx for email Free songs download, http://www.soundclick.com/bands/8/nomessiahsmusic.htm |

All the USB kbs I've seen are really expensive, and I don't know anybody with one. A PS/2 device must be designed accordingly to work with a USB adapter. I'm "guessing" that one can't. Do you have the opportunity to test the PS/2 port's power? By that I mean taking a voltage meter and/or continuity meter and checking for 5V, making sure that port's fuse isn't blown. I know my bits and bytes (I'm a programmer by (would-be) trade, but I don't know a volt from an ohm! Well from a blurry picture I just saw, at least it looks like PC Chips put a fuse on that board... some of the newer boards omit the fuse, put a solid jumper wire where there was a spot for a fuse... I guess that cut their costs by a few cents, but it's a shame they couldn't just raise the cost of the board by a dollar or two instead of taking such shortcuts.

I had trouble finding info on this board when I first got it (unmarked boards!) so I don't have a link sorry. Try changing the keyboard power-on jumper. I don't know where it is on the board, possibly right next to the PS/2 port. Some PCCHips/ECS boards have a row of jumpers to allow aux PS/2 control for proprietary/special uses... these jumpers are dual-purpose, as headers a cable can be attached for infrared keyboards and such, but for using the rear PS/2 ports it's necessary to put a jumper over the correct pins. Your board may not have these pins, and if it does, it's VERY important to not just start trying different jumper locations, because IIRC, some of the pins are power, can damage the board if jumpered to pins next to them. Unfortunately I don't have the pinout, might be able to find it, but from the blurry picture I saw it didnt' look like that board has these pins... would be a 2xN row, maybe 14 or more pins, definitely longer than a USB header.
