USB boot and EWF RAM REG

[crus]

Hello all,
I have installed XPE image ( FP 2007) on a USB stick and boot from it.
It's rather slow, but it's nice.
I have EWF RAM reg mode and if protection is enabled it boots faster ( about
1 min. for 300 mega bytes image).
I can't disable any more EWF, since command
-disable
or
-commitanddisable hangs up the computer, that stops to reply. I only can
shut off and restart.
EWF is still enabled.
Has anyone checked EWF and BOOTUSB?
regards
Raffaele

Raffaele,

EWF RAM Reg mode works quite well for me on all USB images I created.

If you want an intermediate (dev) solution, you can open up the image's system registry hive offline (from another OS such XP Pro)
using regedt.exe/Load Hive function. And disable EWF there by setting the appropriate registry value to 0:
[HKLM\System\ControlSet001\Services\EWF\Parameters\Protected\Volume0],"Enabled"=dword:0.

Konstantin,
the procedure you suggested unlocked the stick.
I also tried to reset the same key on XPE itself, but it restarts with EWF
still enabled.
I must say that the FBA phase has been done on a CompactFlash and not on the
stick itself, to speed up operation. The first, and only time I did on the
stick it took about 2 hours!!
After that I do on the CF and at the end copy all files onto the stick.
CF and stick are both FAT32 formatted.
Perhaps some disk architecture for EWF is different.
Any idea to reduce the FBA phase time? a faster stick of course, but all
I've checked are slow.

Raffaele,

Unfortunately, there is not much you can do to speed up the FBA process on USB stick. Obviously, only use USB 2.0 devices and make
sure USB 2.0 Boot component stack is included and resolved in your runtime config.

It is still weird the behavior you are seeing with the EWF on the stick. Does the same behavior your are seeing on the image
directly deployed and ran through FBA on the stick?
What happens when you just issue "ewfmgr c: -commit" command on the image running on the stick?

Also, when you copy image from CF to the stick make sure to enable EWF only on the stick. In other word, please have EWF disabled on
CF.

Not all USB flash disks are created equal. Some have fast controllers so do
not. I am starting a list to capture this information:

If FBA is taking 2 hours, then you have a slow controller.

Konstantin,
The EWF behaves OK ( no lock) on the CF using the same image.
To exclude the CF copy I did again FBA on the USB stick, than the behavior
is as follow:
EWF disabled:
ewfmgr c: -commitanddisable ( useless but gives reply )
ewfmgr c: -enable ( 5 seconds to reply )
REBOOT
EWF is enabled
ewfmgr c: -commit ( correct reply)
ewfmgr c: commitanddisable -live ( reply and disable at once EWF!!, I never
checked before)
efwmgr c: commitanddisable ( the system hangs, I should shut the power off)
on next boot EWF is still enabled
Since disable -live is better, I'll do with it, perhaps the the poor writing
performance of my sticks is the cause, in what differs life and boot time?

Sean,
I'm using TwinMos Mobile Disk M1 USB2.0 and LG USB Drive Silver both are
2.0. During transfer I read speed: near 9 Mb/sec read, and 1Mb/sec Write.
( ms recommends 9Mb/sec write!)
Both are much faster when EWF is enabled.
I plan to use PQI U350H, I'll report if it give better performance.

The reason it is fast wtih EWF enabled, is because all writes are going to
RAM instead of the slower flash controller.

The Memorex Travel drives have very good performance.

Raffaele,

That hang would be due to the stick hardware performance If you said the issue is there when you do the -live commit.
That basically means if you leave it for a while after the -commitanddisable -live command was issued it will eventually commit the
changes and return the system to a working state.

However, the command you issued (just commitanddisable) was suppose to commit the changes at shutdown time. Since you indicated it
hangs right after you issue the command I can only suspect there is another bug in the EWF driver implementation that you can see
with your hardware. Perhaps escalating or reporting this issue to Microsoft would be a good idea here.
