Specifications for the Compaq 12XL125 state that the system memory is:
64 MB 100 MHz SyncDRAM, shared memory architecture, upgradable to 192 MB - 4 MB dedicated for video memory

This system will not be able to use the ram you are trying to install.  For more about this system go to this link:

    Yes, it would run better on Win 98. There is a "sweet spot" or ideal amount of ram for each operating system. For Win XP it is 512 MB of ram.  That does not mean it would not run on less.  It just runs slower than it could if it had its ideal amount of ram.  This system would run well in Win 98. It was probably built for Win 95 "back in the day".  The optimal amount of ram for Win 98 is 256 MB but it will run very well on a lot less.

Can it be made connected to wiFi?

Chris Sessions, you could purchase a wireless adapter for it for about $15 pretty much anywhere. Just keep in mind that this laptop does not have a lot of RAM or hard drive space on it.. In other words, if you see that its too slow to search the web you need to do a lot of upgrading on it to work better for you..

Too slow Compaq Evo Pentium 4 1.60 GHz 256 MB of RAM

Try re-install the operating system . If windows xp you wanted, try using the first/SP1.
Most of all older machine with low spec,mostly slow . but not that slow if choose the right system operation. i suggest try install windows 2000 for better performance.

    Presario won't recognize second 256 RAM

    Remove the original module, install just the new one and then start your computer. If it doesn't start, the memory you bought is bad. The system boards used in the Compaqs will auto-detect memory, and there are no jumpers or BIOS settings needed.

    What are the ram limits on a compaq presario 5000a. I put 256 ram in the compaq and it only reads 128. Why?

    You can install up to 3 sticks of 512 mb of memory. Did you add a 256 stick to the already-existing 128? You need to put DDR266/PC2100 memory. To troubleshoot, remove the 128 stick and put your 256 in and see if it is recognized. You will know right away from the bios screen. Memory needs to be the same type.

    The Bios on the laptop motherboard only will recognize a total of 1gig Ram. So the 256 stick would be removed and 2- 512 sticks installed.
