Dimension 8400 boot from SATA PCI-e card
I have upgraded my 8400 with an SSD with only a slight increase in performance due to the SATA I interface of the machine, my question is will this card work and will I be able to boot from it?http://www.newegg.com/Product/Product.aspx?Item=N82E16816124068

It's even more complicated...
The PCI-e SATA board probably requires a software driver to work, but the driver can't load unless / until Windows loads. So the boot manager won't ever see the card, and there's no option for PCI-e boot in BIOS in the D8400 anyway.
The PCI-e card can't accept data from the drive at 250 and push it out to the bus at 150. Where's it going to store data that's coming in faster than it can push it out? So even if you could boot from PCI-e, it's still not going to be any faster than SATA1.
EDIT: Just looked at your link and -yes- that card comes with a driver CD, so it can't boot the system because its driver isn't loaded.

Short answer is no.Wont work at all.

The card is PCI-E 2.0 bus you have PCI-E 1.0 bus.
So adding this will not make your drive speed better.
PCI-E version 1.0 X1 Bandwidth is not up to sata 3 speeds.
PCI-E version 1.0 X4 Bandwidth aka 4 times faster than X1 is fine for sata 3. You do not have an X4 PCI-E slot and you cant use the video slot for a mass storage controller.
PCI-E connectors have been defined for ×1, ×4, ×8, and ×16 link widths, with a transfer rate of 250 MB/s per lane. 4 X 250 MB/s = 1 GB/s
so even X16 card aka 16 x 250 MB/s is limited to 4GB/s.
Theoretical speed is 5gbps (640MBps) Max.
When you get to PCI-E 3.0 its 1GB/s this changes.
Bits not Bytes.

Ah that's more helpful, so the motherboard is SATA I theoretical max of 150MB/s correct? the card is PCI-e x1 theoretical max of 250MB/s and in theory the card should be backward compatible then I should see the speed increase x2, not SATA III but better than nothing, correct?

Can you offer any insight as to why? after all the motherboard has a PCI-e x1 slot and the card specs state PCI-e x1
Simply saying no without any backup info is no help whatsoever.

Mega Bits per second not Mega Bytes per second.
PCI bus is not overhead free. You never get 100 percent of the theoretical speed.
UDMA 133 is the max on pci bus and UDMA 150 is the max on the pci-e bus.The system is TOO OLD and TOO SLOW.

OK thanks, no option to boot from PCIe then no go :emotion-6:
But I am still curious as to why the PCIe x1 slot will only run at 150 when the spec for PCIe x1 is 250?

This has got me thinking now, I like a challenge, what if I was to create a dual boot environment, for example XP on a drive connected to the motherboard SATA connectors, then create the required entries from XP with EasyBCD to show the systems installed on the drive connected to the PCIe card?

LoL your probably right but I still want to know why the PCIe x1 slot will only run at 150 when the spec for PCIe x1 is 250.

SATA 3 speed isSATA III interface (6Gbs) PCI-E X1 is 250Mbps.
This is why X4 pci-e is what you need for sata3 cards that work actual speed.

You cannot put this card in the video slot.

Well, I don't want to put in the video slot I want to put in the PCI-e x1 slot, and as you said PCI-e x1 is 250Mbps, so why would it push data at 150 as RoHe stated in the post dated 16 Dec 2015 1:17 AM ?
If the card runs at SATA II speed that's double what I am getting now so happy day's :)

Speedometer dial in my car tops out at 140 MPH but can my car even go 140 MPH..?? :emotion-2:
I installed a SATA2 replacement HDD in my D8400. Do I get SATA2 speed out of it? NO...

SATA Revision 2.0 is often called SATA II and has a maximum theoretical bandwidth of 3 gigabits per second. SATA Revision 3.0 is sometimes called SATA III, and has a maximum theoretical bandwidth of 6 gigabits per second. Sata 1.0 is 1.5 gigabits per second. If you're using a mechanical drive, your drive is the bottleneck. If you're using an SSD on a 3Gbps SATA bus, the SATA bus is the bottleneck. If you're using an SSD on a 6Gbps bus, you're probably limited by the drive speed, but if it's a very fast SSD you're bumping up against the limit of the interface.
The 150 or 300 or 600 meg data transfer rate is theoretical not absolutely guaranteed rate.
