I need to enable AHCI to my dell optiplex GX280 with the BIOS version A08

and old DELL, GX280.
why post lacking what kind and size memory now? 1GB? 2GB?
or if replacing it all so it all matches.?
buy it on crucial.com> they know what it holds.
but you never told full name of PC>
first off it is and old OptiPlex. came with windows 2000 ,omg./
some sold 2005 year so is 14 years old,. today.
Any 3020 is far newer and better,.$50 cash easy .....
why mess with any 2005 PC?
this PC came in 3 sizes,
SFF, , small desktop and full desktop . what might yours be?
the motherboards are NOT THE SAME>
DDR2 memory it is.
400 & 533 MHz DDR2 SDRAM

when pC was new only 1GB sticks were max size.

4GB max but the SFF is 2GB max, see?
4 slots of DDR but 2 only on SFF
SFF = small form factor PC. dinky do case. ok>?tiny

what works can be hard, on old PCs
old PCs have very tricky memory density limits per stick.
ok?>
That is why buy from only a place that allows fast , simple
exchanges or refunds. ok?

That error is a boot device error and you need to check the BIOS to see what is listed for hard drives and other devices and see if AHCI is enabled etc.

Hi,

It makes no difference providing the computer motherboards support SATA interface.

SATA 1 and 2 drivers are in the BIOS. If all the computers have SATA 1 you can upgrade the BIOS to latest version via Dell's support website.





Regards.

remove the cmos battery from your motherboard and return it again after 5 seconds, that will restart your BIOS, or you look for the BIOS reset pin on your motherboard just consult your manual as guide.

eykraus,
I have some experience in upgrading your Dell.
If this gx280 was my computer and want to upgrade I'll only go to 3.0 but you need to upgrade you bios to support the new upgrade. You could also upgrade the memory as well. Put the power supply you have in so you can conserve.

Sound like you need to go to Dell's website and download the drivers for the video card and the sound card. If they have updated version of the bios for your computer that probably wouldn't hurt either.

No compatibility problem in your case. XP should work well with Dell optiplex gx280. Try re-installing the OS, there is problem with the OS version you had used to install.Rate me if it is useful!!

If you never set up a password try Admin

Is something broken?

If it isn't, don't fix it.
You should be ok not updating.
