162 System options not set?

March 31, 2011 at 01:45:45
Specs: Windows XP, 512 MB
Ok on boot the computer counts the ram.... Then after a few seconds it displays 162-System Options Not Set. I have replaced the battery... No effect... I have tried to enter the bios by pressing F10 it displays "Entering Bios Setup..." then beeps twice then Displays again "162-System Options Not Set" and freezes there, it does not move on... Now what I did was pulled out the battery and this started happening. I have done research on the error and it appears that I need to flash the bios but I cannot find the computer on the HP or Compaq site. I upgraded the computer from 98 to XP last night, everything worked great until I pulled the battery out.

Model Number: 7594
Compaq Serial Number: 2H05DCV9JODK
Name: Compaq Presario Agency Series CM0900

I cannot find the bios floppy utility after extensive searching on google and the HP and Compaq Sites.
Any help on this matter would be great thank you.

Why did you remove the battery? Doing that resets the CMOS to default, basically. Did you Google that error? I found these among others:

"I have done research on the error and it appears that I need to flash the bios ..."

Everybody and their dog suggests you should flash your bios when they don't know how to fix your problem !

You DO NOT need to flash your bios !

It MAKES NO SENSE AT ALL to flash your bios if the bios version you presently have gave you no problems at ANY time previously !

error 162 = system options not set - for some bios versions is the same thing as the CMOS CHECKSUM ERROR you get with other bioses.
All you need to do is go into the bios Setup and set the Time and Date to something other than their defaults, preferably the current date and time.

If your cmos battery were too weak or dead you would ALSO get error 161 = dead or too weak battery

Sometimes you need to press the key to enter the bios BEFORE the bios freezes.

If you are using a USB keyboard, Legacy USB or USB keyboard or similar must be enabled in the bios settings in order for you to be able to get into the bios Setup with a USB keyboard.
If your computer has a PS/2 port, you can always get into the bios with a PS/2 keyboard.

If you can get into the operating system, any operating system, setting the time and date in the operating system with usually automatically correct the time and date in the bios.

I am not using a USB Keyboard and it does not give a 161 error just a 162. I have bought a new battery and put it in no change... 162 error still. I press F10 at the correct time and it Displays "Entering Bios Setup..." Then Displays the 162 Error and Freezes.

"I cannot find the bios floppy utility after extensive searching on google and the HP and Compaq Sites."

This computer DOES NOT require a floppy to access the bios Setup.

The last PC computers that required that were the early 286 cpu computers that were made in the late 80's, early 90's possibly.

I did some research and it probably IS F10 you need to press to get into the bios Setup, because that's what it is for the Presario 74xx series.

Try pressing F10 repeatedly starting just after the memory count starts.

If that doesn't help, or in any case

Getting the 162 error SHOULD NOT freeze the bios and prevent you from getting into the operating system on the hard drive, if you have that.

I suspect you have some other problem

One or more of:
- you have incompatible ram installed in the mboard.
E.g. this mboard probably can use max 256mb SDram modules in each ram slot, and 256mb modules probably MUST have 16 memory chips - 8 on each side - not 8 on one side - modules with an odd number of memory chips - 9 - on one side or on each of both sides may NOT be supported. (The memory chips are all the same size - there may be 1, 2, or 3 additional smaller chips.)

- you are trying to use a hard drive of a size larger than the max size the model originally came with that is not recognized properly by the bios version - some older bios versions made before 2001 (your computer was probably made before 2001) have bugs that will freeze the bios while booting in that case.
There are bios bugs that affect drives larger than binary size 8.4gb, 32gb, and 64 gb. In this case your bios version may have either the one(s) for 32gb or 64gb.

In any case,the main chipset cannot recognoze drivers larger than 137gb manufacturer's size (= 128gb in the bios and in Windows) as their full size even if the bios version does not have bugs (they are recognized as128gb max).

- you have one or more IDE drives jumpered incorrectly

- you have a problem with your IDE data cable(s)

- you may have one or more dead drive

If you disconnect the hard drive(s) if that applies, or all hard and CD or DVD drive(s) if that applies - the data cables - you should be able to get into the bios Setup no problem, if you have not installed incompatible ram,
- and a bootable floppy in a floppy drive should be detected fine, if the floppy drive is connected properly, there's nothing wrong with the drive, and the bios Boot Order or similar settings list a floppy drive first.

"I cannot find the computer on the HP or Compaq site. "

You didn't try very hard, assuming you quoted the right model number.

Compaq Presario 7594 Desktop PC - Product Specifications

Compaq P/N - 189713-003
That's probably on a label on the outside of the case.

If yours has a different P/N (part) number, tell us what it is.

There are no manuals there, however, I might be able to dig up one, or more than one.

Your model was made by Compaq BEFORE HP merged with Compaq.

"Okay I have switched out the ram I now have a 164 Error "Memory Size Error" :S "

At least one module you installed is incompatible with using it in the mboard !
Put the original ram back in it !

You don't need more complications.

Try the other stuff I suggested in response 8.

Same thing, original Compaq document name :

Motherboard diagram at the end of it.

Says max 512mb memory.

Kingston lists max 256mb modules per slot in their discontinued model / module listings.The system came with either one 64mb module or one 128mb module.
They're probably PC100 SDram modules.

Sometimes the Maintenance manual is there for the series but not for the models in the series - in this case no such luck.

This is the original Maintenance and Service Guide for the Presario 7500 series that was on the Compaq ftp web site - over the years HP has lost it , both on their web site and on the Compaq ftp web site, which still exists
but there is not as much there as there once was.

MSG-7500.zip here:

The archive unzips to a folder labeled 7500.

It would be a good idea to make a new folder with a name such as MSG Presario 7500 Series, unzip the archive contents to that folder, and make a text file tittled ReadMe or similar in the folder with this in it - "Double click on index.html in the ....\7500 folder to examine the manual properly."
which is what you need to do.

More on the RAM. if you have multiple slots, first thing you should try is moving the RAM to the other slots. If it is not slotted/seated properly, this can also cause major issues
