I'm doing maintenance on a HP DC7100 Small Form Factor.
After reinstalling Windows XP on the machine, installed all the drivers I then decided to upgrade the BIOS firmware.
It all went well, but, by mistake, I shutdown the computer after it restarted and displayed the initial boot information.
Now, when I try to boot up the computer, it keeps beeping.
It beeps 9 times (including front red led).
After searching on Google for the beep codes table, I found out it is due to bad ROM (BIOS).
I then read on how to fix it without replacing any component. I found out Rompaq Diskette. Hmm, how to boot it then?
Searched again and some people say to use a PS/2 keyboard, which I use to be able to boot the diskette. Pressed Windows+B in various timing combinations, but it keeps on going for the beeps and does not load the diskette information.
Any help would be appreciated, since the computer isn't mine and I don't want to end up on a dead computer.
EDIT: I already tried clearing the CMOS, and it didn't work either.
So you shut it off before the BIOS upgrade was complete? – Ƭᴇcʜιᴇ007 – 2013-05-27T16:19:44.923
Sure hope you didn't end up bricking someone else's PC. What's Win+B for, to boot from the floppy? – Karan – 2013-05-27T16:20:08.473
@techie007 I guess, because it ended up doing that after I shut it down before it finished loading Windows XP. – silentw – 2013-05-27T16:21:20.367
@Karan that's correct! – silentw – 2013-05-27T16:22:38.310

According to this document, 9 beeps means “Wrong power supply input voltage”, and invalid ROM checksum should result in 8 beeps — are you sure you hear 9 beeps? However, the Technical Reference Guide says that 9 beeps means ”System powers on but fails to boot” on page 7-5 (137 in pdf).
