    Thanks Wraiith303 and 1234c282. You are really quick!

    The existing HD is Quantum Fireball 3.5 Series, 5.1 GB, ATA interface. Motherboard is IBM dated 1999, 614H2511. Product and BIOS details see at pic enclosed. Replacement HDD I have is 10.1 GB Fujitsu made for IBM P/N09N0970, model MPF3102AT-B2 mfr date 22MAY2000 or I find something over 20GB.

    However 1234c282 made remarks on OS and I admit it is XP I am running now. Is my mission impossible?

    With specifications like that , id be very careful about what size hard drive you try and put in it. Throughout the years , there have been different limitations of hard drive size that the operating system can actually see and use.

    how big is the drive you are trying to install? It seems a shame to tell you how to fit it if its not going to work.

    In general, computer systems with a BIOS dated 1998 or later can work with drives up to 32 gigabytes (GB) in size.

    In addition, in some computers, a 64GB barrier is still to be overcome.

    The maximum size of any one file on a FAT32 drive is 4 gigabytes. Win98, WinME and Win2000 all support the FAT32 file system.

    So what this seems to boil down to is that you need to have the most current BIOS in your system and an operating system that supports the large drive you want to install. If your computer has an older BIOS (before 1998) then you need to see if a more current BIOS is available from the computer or motherboard manufacturer. Motherboards built in the past few years generally have a flash BIOS that can be upgraded. If you cannot upgrade the BIOS, then the alternative is a third-party software solution or an IDE controller board.

    Please Provide the size of the drive you are thinking of putting in , and also the make model and date of the BIOS , which can be accessed by pressing a certain key at system boot up. Generally its one of the function keys , F1 or F2 possibly but its hard to say as the button varies with each computer. Also , if you can find out the make and model of your motherboard and the operating system that you are running eg Windows 98 , Windows 2000

    You shouldnt be running Xp on that system if thats what you are running now by the way!

Id downgrade to about windows 2000 or 98 mate because xp doesnt like CPU's under 1ghz. Im guessing that your computer is a bit slow yes? with this specification running xp?

You will get such a more reliable and faster computer.

Id actually say you will be alright with a 10gb drive and possible 20gb but like i previously mentioned there is a 32gb limit for FAT32 drives which you will have if you do downgrade to windows 98 or 2000 as only xp supports the NTFS filesystem. So nothing bigger than that i suppose , although you could buy an IDE controller card which plugs into a spare PCI slot on your motherboard and offers more IDE ports and also supports something called 48bit LBA which allows for drive bigger than 120gb i think. My own HP system cannot have a driver bigger than 120gb as the main system drive but can have any size i want as the slave drive. I haev a 120gb as my main drive and a 320gb as my slave drive.

    Another qwuick note , just had a look on the ibm site. You have bios revision PJKT38 and the latest is PJKT41A. However , i found this in the changes

    - Alert-on-LAN enhancement
    - Support for large hardfiles, over 64 GB
    - Fix modem failure on COM2

    Looks like you can have up to 64gb drives , this was resolved in the BIOS release previous to your current one. I do not recommend updating to the latest version though , unless your operating system hangs during shutdown as stated below in the release notes:-

    - SMBIOS: Add support for new 596B CE revision
    This change should only be considered if your operating
    system is hanging when you do a shutdown.
    Take note that if you do have this problem and apply this
    fix and then flash back to an earlier BIOS level the
    shutdown hang problem will come back.

    If you do decide to upgrade it and something goes wrong , i cannot be held resonsible but heres the link

Is it IDE or SATA? Put the Hdd in your pc, on IDE, the wide ribbon cable is for data, it can only go in one way, and power is the molex connector. 4 power points, ussualy 4 wires. orange, black, red, black, yellow. can only go in one way. thats it. Make sure that if you are running cd/dvd roms and you have 2 hdd's, that the two hdds run on the same ribbon cable, and the cd roms on their own cable. also put the new hdd to slave. (you change it via jumper settings, ussualy printed on the hdd itself)

SATA is easier. you need two cables. sata power, and data. they can also only go in one way. google sata connectors if you don't know how they look. though, if i is a PIII board, i doubt it'll support SATA, so you'll need to buy an IDE hdd.

I have a GPS navigation system ITEM NO W3G-01 which was given to me. Can this be used in the United Kingdom? If not what can I do. I do not live in the States Or Canada. I live in LONDON, UK

In the product manual it indicates there is a SD card slot, along with a USB port, so there is a physical method to change the map data to your locale.
However, you should contact the manufacturer to see if their firmware allows you to change/add maps. Garmin GPS units have this capability, and I have used their topo & Road maps together with very good results for off-road adventures out in AZ & Utah.

There is no PC interface, the USB cable was included should there be any downloadable firmware updates. There are none and they will provide appropriate drivers for the GPS if and when they are available. Updates will be listed in their Support web when available.
