 I want to disable some devices in bios/cmos but it doesn't show at start when I held down the "del" key. What else can I do?
All it gave me was "F1 BOOT" at bottom left hand corner, that is all it gave? When I held down del key, it displayed keyboard error at start of screen, ie "0E-101 keyboard error"..etc. I tried to get in cmos many times but unsuccessful. Please help!
   I don't know if I have deleted bios after install win95 over win3.1, the reason why there's no cmos/bios. Any suggestion appreciated.
 My pc is:  Compaq Presario DX-2 50Mhz, 340mb, 24RAM, 486pc

F1 is also a key to enter the BIOS, just in case you haven't tried it.(DEL & F1 are the two standards) If that doesn't work, you can pull the battery out and short the battery's socket connection (with a screwdriver or what not) this will also clear the BIOS and let you start over. When you turn the power back on, it will give you a CMOS error and take you into the BIOS. Shut the machine down, Reinsert the battery, and away you go.

Good Luck!

  When I run the diagnostic test, the result showed that my pc doesn't support cmos, bios doesn't support hard drive, what should I do?

Did you put the battery back into the system? If so you'll have to re-configure the BIOS manually.

What do you mean by "sort" the battery with screwdriver?
I'm not sure where battery is located, I think it's a round piece of medal inside pc. Beside it there's about 3 tiny pins like pins on a jumper.
  How to get in cmos/bios, by removing battery? How do I sort? Do I tap the pins with a screwdriver? Will that short-circuit the system? Help! I'm a genuine novice, please tell me step-by-step . Thanks.
ps: don't want to muddy the water. :> appreciated!

I just found out that my battery(lithium type) on my mboard is soldered permanently and cannot be removed without a technician. I don't have an external battery so I can't remove the battery.
AHHHHHHHHHHHHH. I guess I can't reset cmos/bios.
   But I think I have one last thing to do, to sort the battery but How? Can anyone tell me, ie power-one or off? What appropriate equipment do I need to sort? Last, will it harm the pc?

There may also be a jumper you can set that will clear out the settings.
Check the motherboard documentation.

Try putting a jumper over the pins by the battery. It's a 90% chance that its the right one.
Even if it isn't, it won't do any damage.
Turn the system on with the jumper in place. let it boot as far as it will go.
shut down the computer, remove the the jumper, and restart.
That should work!

Nope! Nothing happened when I put the jumper on the pins. Win95 starts up as usual and nothing happens even when I remove the jumper.
 Any more suggestions about how to get in cmos of a pc that doesn't seem to have anything except a hard case. No batteries, no cmos, no bios, however the pc still runs. I don't know.

Some computers use Ctrl-Esc, Ctrl-Alt-Esc, Ctrl-S, Ctrl-Alt-S.

Try each of these combinations.

Have you tried calling the manufacturer of the PC?
