Q) How do I enter the BIOS on my Presario?
A) Normally, hitting F10 at the Compaq logo (cursor to upper right corner)
at bootup. If this does not work, it means you have an earlier model, 1996
or earlier, that retains Setup info on a small non-DOS partition at the
front of the hard drive, not in ROM, and this partition is damaged or
missing. Most Commercial desktops/notebooks (DeskPros, Prolineas,
Armadas/Elites, etc.) also have this partition. If this is the case, go
Select your model desktop or notebook and download the Softpaq for Computer
Setup. Run this SoftPaq and it will create a boot floppy from which you can
enter the BIOS. You might want to download the Personal Computer Diagnostics
SoftPaq as well.
Q) Can I disable the onboard video/audio on my Presario and install
A) Yes. As for video, installing the new card normally will disable the
onboard video. Sometimes, you may have to reset your video to Standard VGA
in Device Manager in Windows first, then shut down and install the PCI video
card. On Presarios with an AGP slot, this is not necessary.
The onboard audio is disabled in Windows device manager, then shut down and
install the PCI audio card, reboot and install the drivers.
Q) How do I get QuickRestore Discs for my Presario?
A) In the U.S., call 800-841-2761. Have your model number or serial number
(it's usually on a white barcode sticker on the back or side of the PC).The
cost is $10 for the discs.
Outside the U.S., contact Compaq support in your region for more info.
Q) How can I reinstall my audio (or video, modem, etc.) driver or specific
software without doing a full restore?
A) Most newer model Presarios have a Selective Restore Option. Double click
on the Compaq Support desktop icon, or select it from the menu. Select
QuickRestore, then Selective Restore. you can then select which driver(s) or
software you wish to reinstall.
NOTE: If you have upgraded the operating system or if the Compressed Compaq
folders (CPQDRV, etc.) on the System Save partition have been deleted, or if
the Presario model is an older one without Selective Restore, the above may
not apply. In this case, check the website link above to see if the driver
is there for your model and OS. For software, go into the icons directory on
the QuickRestore CD and and open each image. Once you find the image for the
software you wish to reinstall, then the file name is the directory name of
the software install directory.
That said, some of the programs are not separately installable.
Q) I've installed a new hard disk (or CD-ROM/DVD drive) in my
Presario/DeskPro etc., and it is not recognized. Why?
A) Compaqs come with Cable Select IDE cables. Any drive attached to them
must be jumpered CS for Cable Select. You will also have to partition (using
FDISK) and format the drive before it will be recognized.
Q) I've installed a new 80 GB hard drive in my older Presario, but only 8
GB is recognized. Where is the other 72GB?
A) Unfortunately, many older Presarios ( Pre-1996) have an 8GB hard drive
size limit in BIOS. There are no BIOS upgrades from Compaq to raise this
limit, however, there are two ways to overcome the limit:
1. The best way is to install a PCI IDE controller card with its own BIOS.
These cards are not expensive, less than $50, and also allow full ATA100/133
transfers as well. Promise and SIIG both offer these cards.
2. the other way is to install BIOS overlay software, available from the
hard drive manufacturer's website. This method will slow down drive
Q) Can I put a different motherboard in my Presario?
A) Yes, but not really. The problems would be many, including:
1. Physical layout. Finding one with the same Input/output connector layout
at the back would be very difficult.
2. Onboard connectors. The front panel wires for the onn/off switch and hard
disk/power LEDs go to a single connector designed to fit the pins on the
current board. So, unless you feel comfortable cracking connectors or
re-splicing wires, don't try it.
3. Power Supply connectors on earlier models may be proprietary.
So, generally speaking for most users, the board is NOT easily upgradeable.
Q) How do I prevent getting Blue Screens or freezeups while using the Compaq
A) Look for a file named SCSI1HLP.VXD(or SCSIHLP.VXD) in the
Windows\system\iosubsys directory. If there, rename it toSCSI1HLP.OLD, then
Q) Is there a different or later BIOS for my Compaq that allows more
A) The only BIOS updates that are safe for your Compaq are those listed for
your specific model on the Compaq/HP website. Occasionally, a BIOS update
from Compaq will provide new settings, but not as a general rule. Installing
any other is risky and may render your Compaq unbootable.
Q) Is my Compaq Compatible with Windows XP?
A) There is a compatibility app on the MS site. It attempts to examine all
installed hardware and software and to let you know if you might have a
problem. It's fairly conservative and may warn about things that might later
prove to be trouble-free.
Also check to see if the Compaq website has XP drivers posted for your
Q) How can i uninstall MSN Messenger on my Windows XP Compaq? It does not
show up in Control Panel, Add/Remove Programs, Windows Components.
A) To make it visible, you first must make a slight change in Sysoc.inf in
the C:\Windows\Inf directory. The line now reads:
make it read:
In other words remove "hide" from the line. Then be sure to save the file,
exit notepad, then go to control panel and it will be visible so you can
uncheck the box to uninstall it, which merely removes the entries for it
from the registry. It does not remove the folder from C:\Program files.
You can always reinstall by going back to Control Panel, Add/Remove
Programs, Windows Components and rechecking the box.
