Go buy one, cost a couple dollars, maybe, and having a spare K/B around won't hurt, it needs only to be a cheap one, but not the cheapest available, unless your cashed up, then have a spare flash MS one for when coffee is spilt into your main K/B, you will need one then, my spare MS K/B is literally within reach.
Little things like the incorrect time and date (as when battery was removed) will make the board think it's 50 years or more old, it simply won't come out and play because you will get a Checksum error, wrong time and date, you must reset the bios first, it's easy done, even try again with the USB K/B but hit F1 at the error message, that is once you get back to the error message.
The system will simply not work until the bios has been reset, if you don't know how this works grab your m/b manual, most are basically the same, once the time/ date / installed hardware / and some added USB ports and especially the boot order, good chance it has reverted to the defaults which are not what you have there, so the HDD freaks out, other O/B devices need to be either enabled or dissabled depending on what you have there.
Surely you have a mate that has a spare PS2 K/B ? I have half a dozen of em.
This PC I'm using is #3 in a set of 4, running off a 4-1 KVM switch, OK, my #4 (by something in the build) will make it spit up the no K/B error if the K/B wire is removed from the KVM, once that happens I hit F1 and all is back to normal, I don't need to go into setup, my battery has not been moved, yours has.
I know the NO K/B error message well, I am guessing that you always went into setup ? rather than going Via F1, if you do that it will spit the no K/B error each time out of setup, F1 fixes mine so simply.
The drivers for the USB socket don't load until the O/S starts up, once you get there you should have no more problems, XP itself should fix it, (unless) you do have a hardware fault, it does happen, ain't computers fun ?
