2nd SATA drive wont be recognised

Specs: Windows XP Professional
My new 2nd SATA 11 drive wont identify in Bios. It would be nice to add it permanently as extra storage rather than as an external drive in a cassette. The new drive does format and can be read separately in separate USB cassette drive so drive is sound. I am trying to add it to an established XP setup. What do I need to do to get the BIOS or Windows Explorer to identify it when installed internally. Cables have all been checked.

Go to bios and make sure all sata ports are enabled or set to auto after that save changes then restart the system.

"Product: first international / Mobo id is 09/24/2004-pm 800-8237-6a7l2f0ac-00"

That's not the mboard ID - it's the bios string, and bios strings usually have no spaces in them. Bios strings don't necessarily apply to only one mboard model.
Bios strings are the specific bios version. When it has a date, when you flash the bios with a newer or an older bios update, only the date changes.

09/24/2004-pm 800-8237-6a7l2f0ac-00 should be:


I searched with the later...

Motherboard Name FIC P4M800/P4M-800M/P4M-800T2"

So the bios version is the same for three FIC models.

Open up your computer case and find the model number on the mboard ! It's probably printed in large characters on the surface of the mboard, often between the slots !

Manuals for two of those models here:

Cpu support for 2 of those models here:

What all those have in common is they have the Via PM800 chipset, and they're all older socket 478 mboards.

VIA UniChrome P4M800 chipset

"In combination with the VIA VT8237R Plus South Bridge, the P4M800...... "

VIA VT8237R Plus South Bridge

VT8237R Plus Whitepaper (specs) - it supports only SATA 150, not SATA 300

New SATA drives are SATA II a.k.a. SATA 300 drives - capable of 300mb/sec burst data transfer speeds.
Burst = they can transfer data that fast continuously for only short periods of time, a few minutes at most, how long depending on the size of the memory cache on the drive's board, until the cache is emptied; if the drive continues to be accessed, the sustained data transfer speed is well under max 100mb/sec.

Some older main chipsets that support SATA 150 will recognize a SATA 300 drive but will run it at max. SATA 150 specs.

Some older main chipsets that support SATA 150 cannot recognize SATA 300 drives. In that case, you have to install a jumper on the SATA 300 hard drive to force it to use SATA 150 specs, then the main chipset / the bios will find it fine.

See the label on the SATA drive, or see the manufacturer's info for the model, to see whether the drive has the pins for the jumper so that a jumper can be installed - if it doesn't, return it and get a different brand or model that does. E.g. The Seagate SATA II desktop drives I've seen have the pins and the tiny jumper - it's in SATA 150 mode when you get it - you remove the jumper for SATA 300 mode.

MOBO is P4M-800M/T2

Thanks for the thoughts I will try them out asap

"MOBO is P4M-800M/T2"

Correct CD that came with the mboard ??

Help set up second SATA drive on MOBO P4M 800M/T2. It wont identify in BIOS.?

"...get the first utilities cd,it is 650 MB.the first link below is for the cd,download v1.292.the second link is for the other items for your motherboard..."

(This isn't a drivers related problem. If the VT8237R, or VT8237, can't recognize SATA 300 drives, then you have to force the drive to use SATA 150 specs.)


Says in that:

Via PM800/PM800CE


Northbridge Via PM800 (P4M-800M)
(or) Via PM800CE (P4M-800T2)
Southbridge Via VT8237

(VT8237 - without RAID support; VT8237R - with RAID support.
Generically, you could/can often get the same mboard model with either chip; the mboards were/are usually identical otherwise; use the SATA RAID controller drivers if the chipset has SATA RAID capabilty - actually using a RAID array is optional, and the drivers for a non-RAID chip usually DO NOT work with a RAID chip.)

Compatibility test report......
Cpu, ram, cards, drives, etc.
Says chipset name Via PT800

Via PT800 chipset

Same VT8237R Plus South Bridge

Same VT8237R Plus Whitepaper (specs) - SATA 150 only
