How do you flash the bios on Dell Inspiron 8100

After attempting to regen XP Home and then loading in SP2 from a CD, the system no longer can find a bootable CD or hard drive.  I checked the BIOS and both the CD and hard drive are shown as not installed or none.  I have no idea why loading SP2 from a MS CD would have caused this.  The system was working OK prior to the SP2 install.  Can someone suggest a solution.  I'm assuming that I will need to bring the BIOS back to factory specs with the hope that that will then recognize the CD and hard drive.

i would recommend you to call dell tech support . Updating bios and flash  if not done in proper way will lead to dead motherboard

Also you can try to create your own windows xp bootable cd

Q: How do I restore the default factory settings in the BIOS?

    A: To restore the default settings on the Inspiron 1100, 2500, 2600, 2650, 3000, 3200, 3500, 5000, 5000e, 5100, 7000, or 7500 Latitude L Series Systems, hit <F2> when the BIOS splash screen appears and when the system setup screen appears, hit the <F9> key. Then press the <Enter> key to confirm that you would like to load the defaults. Press the <F10> key to save changes and exit.

    To restore the defaults on the Inspiron 500m, 600m, 3700, 3800, 4000, 4100, 4150, 8000, 8100, 8200 or 8500 or Latitude C, CP, and CS Series Systems, hit <F2> when the BIOS splash screen appears and when the System Setup screen appears, press <Alt> + <F>. Then press the <Esc> key. The press the <Enter> key to save changes and exit.

    To restore the defaults on Legacy Latitude Systems (XPI, XPI CD Series), at the first text on the screen, or the Dell logo, press the <Fn> + <F1> keys simultaneously every three seconds until the message Entering Setup appears. When the System Setup screen appears, press the <Alt> + <F> keys simultaneously to load the factory defaults

In my opinion it is VERY unlikely that this problem is caused by a out-of-date BIOS and so flashing the BIOS is NOT RECOMMENDED.  The risks of installing a no-possibility-of-improvement BIOS update far outweigh any possible benefit.

I suspect that you have either an incorrect BIOS setting (as has been mentioned) but more likely you have a defective system motherboard or drive.  In either case, a BIOS update is NOT going to help.

First thing I would do is enter BIOS and reset everything to to Defaults . . that will often let it recognize the optical drives

From the description you've given, I doubt that either the BIOS or the SP2 install is the problem.   It sounds like the laptop is having a power issue that's causing it to fail to recognize the IDE devices.   Try removing the battery and just using the A/C adapter ==>  if your battery is bad it could be pulling too much current and causing problems that only surface after the system's on long enough for the battery to heat up and overload the charging circuit.

... or try another battery if you have a spare  (but I'd simply run it on A/C with no battery to start with)

Removed the battery and just used AC power to start the system.  Windows came up OK and SP2 is installed.  Thanks.
