SATA drive not detected in BIOS and windows does not boot up

Hi ,
I am using the ASUS K8V-MX motherboard with 80GB SATA drive and Windows XP..
everything was fine until I chose to buy a 500GB SATA and use it.
When I connect
1) both SATA drives : windows does not boot up:throwing lot of errors of RAID etc..
2) connect only 500GB : bios does not detect it

I tried the 500GB SATA in my friends PC and it showed up correctly.

BIOS details are as below
AMIBIOS 08.00.09 Rev 02.01.1711

Any clues what do I need to fix [ update bios ? ]

Thanks in advance...

As mentioned above, you need to either replace your motherboard with one that will support SATAII or you need to find and place a jumper on the HD setting that will make the drive run at 1.5gb/sec. On my Western Digital 500GB HD that was covering pins 5 and 6. Then the Via 8237 and OS saw the drive and I was able to use it.

PrashantP, your board does not support SATAII. As mentioned by Asus:
Qusetion: Why can't my SATA-II hard drive be detected on VIA VT8237 chipset based motherboard?
This may be caused by the fact that VIA 8237/8237R South-bridge chipsets does not provide upward compatibility with SATA-II hard disk drives at 300 MB/s. These HDDs may not even be detected at POST. To install a SATA-II hard drive, users need to lock the drive at 150 MB/s data transfer rate by HDD jumper setting. Please refer to the following jumper setting from HDDs manufacturers or visit their website for latest updates.
Even if you updated your bios it will have no effect.
This is also why your SATA drive is not being seen by the bios.
Anymore questions PrashantP? Just post back here.
please vote...

0501 is the newest beta bios for that motherboard. 0211 is the newest non-beta bios, both from 2006 timeframe with the beta bios being Dec 15, 2006.
Do you have the motherboard manual? That should explain almost all your questions. If not the website address for download of manual is
In some cases there will be jumpers on the motherboard to help with RAID issues, in other cases and with most of the more modern motherboards these issues are pretty much covered in the motherboard bios.

i am having the same problem.. i have asrock k8upgrade vm800 mobo... i just bought a Samsung 160BG SATA 3.0gb/s.. it says on the motherboard's manual, it only supports 1.5gb/s. dunno if it has something to do with my new SATA. i never had SATA. i'm still using my old PATA 40GB hard drive but the one that I just put is not being detected in BIOS... i've heard you have to change the jumper settings... but i don't know how to set it in my newly purchased hard drive.

anyone can help me with the jumper settings. i've tried several combination... that doesn't seem to help.. maybe im doing it wrong i don't know.. i've checked everything in BIOS. nothing to set to detect the SATA drive. everything is auto detect. im not sure if flashing the BIOS a good idea. but i don't want to mess up my mobo. i reseated cmos battery. no go. i went to samsung's website. it says that you have to install a disk management creator (which i download two version of it -- but both didn't work) because older motherboard cannot really detect new high capacity hard disks. after i ran those program (which is saved to a floppy disk - i have to buy a floppy disk for that, guess what? cr*p didn't work) the SATA hdd is still not detected...

i don't know what to do now.. i'm afraid if i downgrade it to PATA 160GB, it may not work either.... i need more room... im runnning out of space.. imagine having a 40GB now adays....hayzz... plss elp me....

SOURCE: ASUS P5LD2 Raid 5 locks windows at MUP.SYS

A stab in the dark. Sound like the MB BIOS expects and is written to have the OS on the  IDE  slot. After that I would add one SATA drive at a time to see if it matters and to see if one of the drives are causing the problem.

Check your jumper settings on the drive. Make sure you 80 gig hard is slave if you want your 500 as master.

Check your AHCI (or ACHI, can't remember) settings in your BIOS. Turn them off, use "standard pata mode" even though you're using a SATA drive, and try again.

Hi, I'm having K8V-MX Asus mother board with AMD 3000+ processor wih 1GB DDR ram, with 80 GB PATA Segate HDD connected. After adding 500GB SATA HDD to this mother board, my system performance is very low....

Thanks for the details. I have used K8V-MX Asus motherboard and found it very reliable with quite reasonable performance. It definately supports 500 GB Sata drive and there must not be any issues after increasing just the storage. However, Operating System upgrade may result in sluggish performance. Drivers dont seem to be an issue to me either.
I suggest to review a few points detailed as under: -
- K8V-MX Asus Supports RAID, so, check for any RAID Drivers/ settings. (You dont have to use RAID for two Hard Drives of different make, capacity and speed). Try using one disk at a time having same Operating System (e.g. Windows XP) and compare the performance.
- Infact SATA Drives have better data transfer rate than IDE, which results in enhanced performance.
- Some Programs (that you may not be using with 80GB drive) Like antivirus may result in decreased performance.
- Please Review you Operating System environment and software installed. Make sure that the new drive & Operating System are free of any virus, which results in CPU Utilization upto 100%.
- Also, motherboard supports Max 2GB RAM, so you may consider adding more RAM.

Let me know if any further clarification/ assistance is required.
Hope it helps! Good Luck!

ASUS K8S-MX Motherboard, but when I connect IDE

How were the partitions created on the SATA? Are they RAID configured from the other system? Does the new motherboard have the same support for your HD as the other system? Check the setup in the BIOS screen on both systems to make them identical as much as you can. According to Tom's Hardware: "In the SATA port configuration place you have up to four "mode" choices: IDE (or PATA) Emulation, native SATA, AHCI, or RAID." Check this section.

K8V-MX motherboard+HDD size limit

yes the mother board supports SATA However if you connect large Disks to the SATA connectors they are recognized correctly with full size. So leave your 500g and less HDs on the IDE and the big ones on the SATA. you can check this link for the manual for more information hope this helps .thanks and Godbless pls appreciate by rating as fixyaa
