USB Flash Boot?

[richard]

Why do we need to mark the USB flash disk as fixed for booting XPE??.
but it works with dos and linux as removable disk. Is there any article
explaining this behaviour???

Cant we set the removable bit through programatically??? b'coz It is
very urgent for me to make a bootable USB flash disk. if we go for
asking the vendor for the utility it may take atleast a week to get it.
pls suggest me.

richard,


You will find sample sample code on how to make your driver to ignore the removable bit on www.xpefiles.com.

Hi Richard,

Before you get stuck in this whithout the option to go back you should consider easier alternatives like:
1. You can boot from SDI (RAM disk) that is loaded from USB Flash to memory by ntldr. (This is easy solution)
2. You can use third-party solutions for XPe like the one provided by M-Systems.

PS:
If time is critical for you then only choice that you have is RAM Boot.

richard,

I agree with Slobodan. If time is critical to you, you may want to go with RAM boot (of course, if acceptable by your system
requirements).
RAM boot you can be implemented pretty quick.

With regards to the driver code.. Start with installing the WinDDK.

Hi David,

I'm not familiar with changes in this uDOC device model .

Have you used uDOCPart tool? From there you can make bootable uDOC that
should work on all motherboards, after you do that just place ntldr. and
following boot.ini for test.

[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="Microsoft Windows XPe Test1 "
/noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XPe Test2"
/noexecute=optin /fastdetect

For simple start use empty project in TD and add "USB uDiskOnChip MinLogon
Macro" then resolve all dependencies and you should be good to go.

In your project (TD) you must include component: "USB uDiskOnChip component"
and resolve dependencies. (but first try universal macro that do not require
you to use TAP or anything else for that matter).

I can't talk in public NG too much about all this, please contact me offline
and keep Nimrod CC (he should be able to help you).
In email you should tell us what motherboard model do you use.

Regards,
Slobodan

PS:
I Thought that you have solved this :-(

David,

I cover the uDOC setup steps in the Windows XP Embedded Supplemental
Toolkit. I am shipping the version of the uDOC that you have mentioned:
MD1665. The software tools that Slobodan mentioned will work with this
version of the uDOC.
