If boot block debugger is enabled, CPU cache-as-RAM functionality is enabled at this point. Stack will be enabled from this point.
D0
Early Boot Strap Processor (BSP) initialization like microcode update, frequency and other CPU critical initialization. Early chipset initialization is done.
D1
Early super I/O initialization is done including RTC and keyboard controller. Serial port is enabled at this point if needed for debugging. NMI is disabled. Perform keyboard controller BAT test. Save power-on CPUID value in scratch CMOS. Go to flat mode with 4GB limit and GA20 enabled.
D2
Verify the boot block checksum. System will hang here if checksum is bad.
D3
Disable CACHE before memory detection. Execute full memory sizing module. If memory sizing module not executed, start memory refresh and do memory sizing in Boot block code. Do additional chipset initialization. Re-enable CACHE. Verify that flat mode is enabled.
D4
Test base 512KB memory. Adjust policies and cache first 8MB. Set stack.
D5
Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS now executes out of RAM. Copies compressed boot block code to memory in right segments. Copies BIOS from ROM to RAM for faster access. Performs main BIOS checksum and updates recovery status accordingly.
D6
Both key sequence and OEM specific method is checked to determine if BIOS recovery is forced. If BIOS recovery is necessary, control flows to checkpoint E0. See
Bootblock Recovery Code Checkpoints section of document for more information.
D7
Restore CPUID value back into register. The Bootblock-Runtime interface module is moved to system memory and control is given to it. Determine whether to execute serial flash.
D8
The Runtime module is uncompressed into memory. CPUID information is stored in memory.
D9
Store the Uncompressed pointer for future use in PMM. Copying Main BIOS into memory. Leaves all RAM below 1MB Read-Write including E000 and F000 shadow areas but closing SMRAM.
DA
Restore CPUID value back into register. Give control to BIOS POST (ExecutePOSTKernel). See
POST Code Checkpoints section of document for more information.
I have the same problem. My 435mt freezes intermintently (approximately 80% of the time) at the dell logo. The times that it doesn't freeze it shows the checkpoint error. I've probably called dell 5-6 times on this issue, reinstalled vista, upgraded my video card, flashed my bios, etc... None of this helped...
But I do have some good news... In desperation, I unplugged all the extra devices (i.e. printer, microphone, etc.) from my computer. Magically, my computer started booting flawlessly! I narrowed down the postential offenders to my multifuntion printer that has an onboard memory card reader. It would seem, that this models bios gets confused by this reader.
One work around: Unplug your printers USB cable.
This afternoon, I am going to try to disable any BIOS settings that try to boot from USB devices.
Ideally, I don't want to have to be meesing around with a usb cable on my brand new PC!!
Well, after a good week or so, the boot diagnostic started coming back, and is now happening whenever I don't F2 into the setup. FWIW, the only post-boot symptom is Photoshop Elements failing after a few minutes, so if I'm just going to do emails, Internet, Quicken, etc. without Photoshop, I just let it give the message. Another call to Dell didn't really get beyond their saying that the next step is to re-install the OS. I give the re-install a small likelihood of success but a huge workload of re-installing programs, etc. I guess I'll just live with it for a while; maybe somebody will figure out what the problem is.
I too am receiving this error with the 435MT. Though inclined to blame Dell for yet another half-witted design, I really am without excuse in that I should have known better. E.g., I have been in IT for many, many years. The first system I worked with was a DEC PDP-11/24. So suffice it to say I go waaaaaaay back.
Why on earth I vacated common sense and purchased this system - or have thought to purchase any Dell product - is up for speculation. I'll plead temporary insanity.
1. I installed a PCI ex USB port to plug in my printer with multicard reader. This fixed the boot up problem.
2. I installed an aftermoarket case fan so that my PC didn't sound like my wife's canister vacuum .. :(
3. I installed a 600 Watt aftermarke power supply, so that I would no longer get the BSOD from being underpowered during graphics intensive games. (Seriously Dell, what were you thinking with the OEM powersupply?!? This isnt a netbook!!!!)
4. I installed a 2 slot Graphics card that echausts its heat outside the case to help with the overheating.
Along with Vista SP2. my system seems to be fairly stable now. Too bad I had to spend nearly as much upgrading it, as the machine costed out of the box :(
Yes, the USB card did wonders as a work around for the faulty bios and DO (B1) error.
Unfortunately, the PC is underpowered (wattage), undercooled (one small case fan), and under QC tested (bad bios), which results in the other problems people are experiencing. To correct these issues see my previous recomendations.

Time will tell.

Just received a 435mt; same message about D0 and Photoshop Elements repeatedly fails.
I tried Dell Support Chat, but just get bad HTML page, no chat.
Not very pleased right now...

BINGO!!!
I called Tech Support and they had me go into the BIOS and Reload the Default. We then checked the result, didn't modify anything, and restarted it.
So far, it has re-started 3 times without the error message.
I also tried Photoshop Elements and didn't get an error, although time will tell on this as it was an intermittent problem. So far so good.

Final solution for my 435MT...
1. I installed a PCI ex USB port to plug in my printer with multicard reader. This fixed the boot up problem.
2. I installed an aftermoarket case fan so that my PC didn't sound like my wife's canister vacuum .. :(
3. I installed a 600 Watt aftermarke power supply, so that I would no longer get the BSOD from being underpowered during graphics intensive games. (Seriously Dell, what were you thinking with the OEM powersupply?!? This isnt a netbook!!!!)
4. I installed a 2 slot Graphics card that echausts its heat outside the case to help with the overheating.
Along with Vista SP2. my system seems to be fairly stable now. Too bad I had to spend nearly as much upgrading it, as the machine costed out of the box :(
Good Luck!
