Please do write an article. I've looked back through the posts on USB boot, and I haven't found the clue I need.
I have a very successful IDE CF image. Now, I need USB boot of CF or pendrive. I can boot DOS on a removable CF card in a USB reader. So, the BIOS is clever enough to do that. I have XPe on a non-removeable CF card, and it boots from the IDE CF slot. I can see any USB CD card plugged into the USB reader and all the files are accessible. I've marked the USB drivers to load at boot time as suggested in earlier posts, but I may be missing drivers needed for booting. The CF card will not boot in the USB reader. I get an error message "A disk read error occurred. Please use Ctl-Alt-Del to reboot." on the screen. Its probably from the BIOS. Maybe it can't read non-removeable USB devices. The CF card is partitioned with a single active partition and lots of unpartitioned space. I've tried two different USB readers, 2.0 and 1.1, but it doesn't matter.
Any ideas are welcome. -- Regards. Mark K Vallevand
But for now: You should use USB disk marked as non-removable.
Also you must prepare disk (fdisk or diskedit, format) to make disk bootable. You must somehow reach phase that XPe is loading.
When you hit BSOD 7B.
Then you need to mark usbehci, usbohci, usbhub, usbstor. To load at phase 0. Also you need to set LoadGroup to Boot Bus Extender so USB is loaded before filesystem load is attempted.
Failing to do this properly will fail with result 7B.
When you hit BSOD you can use kernel debugger to see what part of USB stack is loaded.
Use: !devnode 0 1 it will list all drivers and their relations.
You need to see something like: (usbohci or usbehci)-usbhub-usbstor or you will see what is missing.
Also all entries must be declared as critical drivers.

Many thanks. The one thing I found out just a few minutes before I saw this message was that non removable drives do boot XPe. I'm making progress again. This notes are just enough clues to get ahead.
Is there a way to get NTFS format to work on all non-removable CF drives? I've had very inconsistant results. I have only one non-removabke CF drive with NTFS on it, and I can't remember how I made it. :-(

Problem is not NTFS related. It is more related to BIOS and disk geometry.
For this I have not found universal answer.
You need to format disk on your target device. Try partitioning with DOS and Windows utilities. Use fdisk, format, diskprep for DOS Use diskpart, format from XP.
Trying both approaches should give you higher level of bootable disks.
Dos utilities are relaying on int 13 so using them on target device should yield the best geometry results.

It is non-removable.

It is all prepared, passed FBA and running perfectly when booting from IDE CF. Its a 512mb CF partitioned into 128mb NTFS and rest unpartitioned.
> You must somehow reach phase that XPe is loading.
Here is where I'm stuck now. The BIOS (I think) won't boot this CF. A removable CF with a whole-disk NTFS partition will get past the BIOS.
> When you hit BSOD 7B.
The removable CF hits the BSOD 7B.

Did this already. Except that usbehci isn't there. I found the missing component (USB 2.0), added it, and will try again. I don't think it matters because I think I'm using USB 1.1 hardware.

OK. This is magic I don't grok. How it this done? In the registry I assume. Let me look... I see it. Made that change, too.

I'll add the debug stuff in boot.ini.

Again, I don't grok critical driver.

Well, if I could get USB disk to boot... I normally boot into FBA from IDE HD, then finish setting up the image. Setting up the image includes registry fixes for EWF and USB, preferences, etc. The image is captured and used to make the CF.

Well. the non-removable CF still won't boot past the BIOS. The removable CF will boot past the BIOS, and starts loading XPe. The blocks slowly walk on the bottom of the screen, then BSOD. The two CFs have identical file contents. The non-removable CF will boot from IDE CF as expected. The removable CF won't boot from IDE CF. Weird, huh?

I have not tried yet boot process from removable USB disk. But you must somehow persuade your BIOS to load ntldr. to phase where it will ask you for OS choice in following boot.ini scenario:
[boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="XPe Test 1" /fastdetect multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="XPe Test 2" /fastdetect
If you make it up to this point then your device(BIOS) is capable of booting XPe from USB.
You need to prepare disk with (fdisk or diskpart) when device is connected on USB CF reader, not on IDE connector. It is possible that BIOS will see different disk geometry for CF connected on USB or IDE adapter.
Search for more info on registry key CriticalDeviceDatabase, you will need to populate this with valid values.
LoadGroup or Group, different names for registry and in inf file, but it same value. More info available in DDK.
If you manage to pass this check points then we can talk again.
Also if you continue to pursue use of removable medium. Use remote kernel debugging to see what USB drivers were loaded when you hit BSOD 7B. This is only way for you to know what is not properly loaded and to separate problem to phases.

It looks like the program Windows\System32\autochk.exe (or autofmt.exe) is failing during the USB disk boot. I suspect that I haven't got the CriticalDeviceDatabase correct in the registry. I'm checking it now. It look OK.
Booting from IDE CF and watching with windbg, the image loads the USB drivers usbohci, usbhub, usbstor. These were the critical devices I added. Booting from USB, windbg never sees anything. The image halts before the debugger can be started. The messaage "A disk read error occurred. Please use Ctl-Alt-Del to reboot." is displayed. That message seems to be coming from autochk.exe or autofmt.exe.

This message origin in not Windows XPe executive. It is more likely from partition boot or from ntldr. When switch to protected mode occurs no more Ctl-Alt-Del can be seen.
Have you been able to conduct test with boot.ini successfully.
windbg will connect automatically to your target device, when kernel start loading (if you have set right debug parameters in boot.ini)
Also you can use /SOS in boot.ini to see binaries that are loaded by ntldr.
