I have a soyo techaid diagnostic card. Installed into the PCI slot and started the computer. It shows a D4 error. According to the manual, This error code is ...TO comeback to real mode. Execute OEM patch. Stack. What does this mean?

http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000062532.pdf Here you go.

sounds like a faulty motherboard. try testing the motherboard after removing everything apart from the cpu and ram then add one piece at a time to eliminate one thing at a time.

you need to read what the manual so you can work it out you have three codes to fix first before it will work

CPU = Central Processing Unit. Another term is Microprocessor, or simply Processor for short.
The 'Brain' of the computer.

The Processor sits in a processor socket.
The processor socket for the Soyo SY-KT400 is a Socket A. Also known as Socket 462.

http://en.wikipedia.org/wiki/Socket_462


The motherboard chipset is the Northbridge chip, and Southbridge chip.

The motherboard chipset for the Soyo SY-KT400 is the VIA KT400 - Northbridge chip, and the VIA VT8235 - Southbridge chip.

http://en.wikipedia.org/wiki/List_of_VIA_chipsets#Slot_A_and_Socket_A


The Northbridge chip handles the Faster capabilities of the computer.

The Northbridge chip determines what Processors can be supported, what Ram Memory can be supported, and High-Speed graphics.

High-Speed graphics being AGP and PCI Express, not a graphics card installed in a PCI slot, nor Integrated Graphics.

The Processor communicates with the Northbridge chip through the Front Side Bus. (FSB)
Think of the FSB as an 'Information Highway'.

The Northbridge chip communicates TO the Southbridge chip through the Internal Bus.

The Southbridge chip handles the Slower capabilities of the computer.

The Southbridge chip handles IDE, SATA, USB, Ethernet, Integrated Graphics, and the PCI bus.
(As in a graphics card installed in a PCI expansion slot, for one example)

Also handles information from the Super I/O chipset.
The Soyo SY-KT400 - Super I/O chipset is a VIA VT1211

There are 5 PCI slots. All connected to the PCI bus, which is connected to the Super I/O chipset.

Scroll down a little bit to the photo of the Soyo SY-KT400 motherboard.

A) At the top middle is the Processor socket. White in color, rectangular in shape, square hole in the middle, and socket holes on it.

To the immediate left of the Processor socket are 8 Electrolytic Capacitors in a row.
These capacitors are Radial Aluminum Electrolytic Capacitors. (Used all over the motherboard)

These particular 8 are part of the motherboard voltage regulator circuit.
Specifically, voltage regulation for the Processor.

B) To the right of the Processor socket are three long Black Ram Memory slots. (Proper computer speak for Slot, is Bank. 3 Ram Memory Banks)

C) The Blue and the White connectors to the right of the Ram Memory slots are IDE connectors.
One for the Harddrive, the other one for the optical drive/s.

D) Underneath the Processor is the Northbridge chip. There is a clear fan sitting on it.

E) The large square Black chip with VIA on it, below the Ram Memory slots, and to the right of the purple PCI slots, is the Southbridge chip.

F) The 5 purple long slots are PCI expansion slots.

G) To the right of the bottom purple PCI slot is the CMOS battery.

H) Above the purple PCI slots is a brown AGP slot.
Uses AGP 8X graphics cards

If it just started doing this all of a sudden, then it is a good bet that *********** board is fried. If you just installed some memory or a communications card or new drive, then take it out and see if it still does it. If not, check the installation instructions to make sure it was put in right.

Do you have any pci devices installed? Bad PCI deviced, especailly modems, will cause a PC not to post. Did you try swapping the memory for a different module? It could be the stick and not the slot. Also, are there any blown capacitors on the MOBO, you would know this if they are puffed up at the top.

The 1000-0146 is a diagnostic result indicating a failing hard drive. Just because the drive fails diagnostics, doesn't mean it will not function and is may run for an extended period before if becomes unusable. But take this as a warning and backup any important data you have on that drive NOW.

As far as your PCMCIA Card slot not working.

1. Ensure it is enabled in the BIOS and you have no driver errors in Device Manager.
2. If those all check out, replace the card cage: http://cgi.ebay.com/DELL-LATITUDE-D600-PCMCIA-SLOT-CAGE-CMD3BE7632_W0QQitemZ280331231481QQcmdZViewItemQQptZLaptops_Nov05?hash=item280331231481&_trksid=p3286.c0.m14&_trkparms=72%3A1205%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50

here is the pdf with your user manual from the board.
the pci indeed is the slot for the modem and for the sound card,also.
the pci are slots near the agp slot..shorter than the agp.they are equivalent so you can put the modem and the sound card and to interchange the place if you want.
I think youll find more usefull infos in the manual anyway.
good luck
