Hi Vincent:

Motherboards are built to match specific case (chassis) layouts. I've seen many instances of proprietary motherboards (Dell, HP, Gateway, etc.) being different then the exact same motherboard that the manufacturer makes available to the non-proprietary market.

When purchasing a motherboard for personal projects, I've paid special attention to ordering the correct board (same model number, same printed code on the mobo, etc.) and I've still gotten the wrong board --> it's just one of those things that happens when you deal with purchasing hardware over the Internet.

As far as modifying the Mobo goes...I wouldn't recommend trying it - it's likely that you won't be able to (even if you're pretty handy with soldering and chasing down pin-out connections using schematic diagrams) - I've tried and failed more then a few times - and I have more then a few years of electronics experience under my belt and some formal electronic engineering training to boot!

You're better off returning the board and ordering another one - or...if that's not possible, ordering a different case (they're usually less then $100 if you purchase them online).

Hope that helps...

- Lou

    There should be two different IDE Ribbon cables (grey, flat cables) in your PC - Unless you've got a system with Serial ATA (SATA) devices - in which case, you'll have the smaller SATA cables.

    IDE Ribbon cables can have one or two square drive interface connectors on them - if your hard drive interface cable only has a single square connector on it, you can purchase another double-interface cable for very cheap online or in most tech stores. You can only place 2 devices on a standard IDE ribbon cable.

    The "Slave & Master" jumper settings on modern hard drives are not typically used much anymore. Most modern IDE configurations make use of the "Cable Select" jumper option. This is commonly listed as "Cable" or "CS" on the HDD near the jumper block on IDE cables.

    Cable Select lets the position of the HDD on the cable dictate which drive is master and which is slave. Most IDE ribbon cables have a "Drive 0" and "Drive 1" or "Master" and "Slave" printed right on the ribbon cable - Drive 0 would be your Master, and Drive 1 would be the slave.

    If nothing is printed on the cable - Ususlly (unless you get a funky cable) - the drive closest to the motherboard is the Master, then the one on the end of the cable (furthest from the MoBo) is the slave.

    I wouldn't recommend trying to mix a DVD drive with a Hard Disk Drive on the same IDE ribbon cable - it can be done, but some system don't like this and there are performance considerations - depending upon your HDD conroller, the IDE Bus can dumb-down to the lowest common denominator (if your DVD drive is a slower technology then your HDD, the HDD will perform slower).

    It's normally better to keep removable media devices (CD / DVD / etc.) on one IDE cable and HDD's on another.

    As far as the CD or DVD Audio cable goes - you won't typically need that (most don't even come with external audio cables anymore) - that's an old-school connection that's no longer needed on modern MoBo's.

When I start-up my Compaq Presario S4200NX - I get the Compaq logo and a continuous beep and it doesn't go any further. I've read some posts and its pointing to the memory card being bad. Is this the case?

It is possible that the memory sticks(RAM) are busted or cannot be read anymore. If you have multiple memory sticks, try isolating the damaged memory stick by using 1 memory stick at a time and try starting your computer up. Once you have found the busted one, try replacing it with a new one.

Hope this helps!

I need help installing a second seagate 1tb internal hard drive on a compaq presario sr5502fh? dont know where the data connection for the second hard drive goes.

If you haven't changed the motherboard from the time you bought it, then there must four onboard sata connectors on the motherboard, refer below picture; c24ab14.jpg

If you haven't installed four sata drives, then there must be at least 3, you can connect the new hard drive on any port, no matter Master or Slave, Primary or Secondary, it'll automatically set it for you. You also no need to worry about the cable, both the ends are same, it works on any direction; 80e9306.jpg

Same thing with the power cable, you can join it on any power cable.. daeb671.jpg

I hope this helps, if you have problem with this or if in case your motherboard is different, please let me know;
Good luck.
Thanks for using FixYa.
