|"Dell Dimension E510" is a desktop computer. |
You can easily clear any password that was set in the bios Setup for most desktop computers if you remove the AC power to the computer case, open up the computer case (e.g. remove the left side as seen from the front of the case if it's a tower case; some Dell computer cases have a latch you must move in a certain direction, rather than screws that must be removed at the back of the case on that side), and.....
- remove the Cmos battery on the mboard from it's socket for , say, 15 seconds, and install it again, with the + showing on the battery when it's installed
- or - move a clear Cmos jumper on the mboard to the Clear position, for, say, 15 seconds, and move it back to the normal or run position
- or some mboards have a second such jumper for just Passwords you can move to the clear position and move back to the normal position.
See the Owner's or Service manual for the Dimension E510 if you need more info.
In the first two cases, when you restore the AC power and boot the computer, you will get a message while booting "Cmos Checksum Error" or similar. You must go into the bios Setup and set at least the Time and Date to their current values, Save bios settings, to get rid of that message while booting the computer.
(Some Windows programs will produce error messages if the Time And Date are way out of whack.)
In some cases, e.g. if your computer has more than one hard drive and the bios is not finding a bootable hard drive partition, you may need to change other settings from their default settings in the bios Setup.
"Can't burn iso's"
XP has a simple CD, only, burning program built into it, but it can't make a CD from an *.iso file.
Some third party burning programs you can install in XP can do that, some can't. There are free burning programs on the web that you can download and install that can make a CD (or DVD) from an *.iso file.
