There is this Russian guy, euhenio, that has posted an interesting link on the 911CD Forum:
http://www.911cd.net/forums//index.php?sho...c=19056&hl=

Page is here:
http://euhenio.mam.by/

I tried my best to understand his post after using Systran on that page, but I was still not able to understand the process:
http://www.911cd.net/forums//index.php?sho...181&st=2047

It would be nice if someone could contact him and help him traduce the page, or try the method and report more details in English so that I could jolt down the English version.

The method appears promising, it could also give us some more ideas for Winbuilder

I'm interested to this idea too (I was in DisklessAngel office in Guangzhou and saw it myself - it's working! but I don't like the idea it will be attached firmly to your hardware I can pay for such kind of things but in this case I'd like to have an alternative. And we are discussing this on Ru-Board Forums as well.

I tried the method you mention this night but couldn't get any good results. But I was not following to euhenio's instructions very closely maybe that's why. I asked him a few questions about the process and after I understand it myself a bit better I'll definetely can describe the steps.

Thank you very much.

HighwayStar from Ru-Board (and the member of this forum too) reported yesterday that he also successfuly used this method. Maybe it's better to ask him?

I can't reproduce it... so I'm afraid my understanding maybe wrong and the rusulting translation can only confuse you...

I've read euhenio's page.

Though, his instructions are rather unclear, I think I got his idea, which is:
- Modified (by him) GRUB4DOS reads RamDisk image into memory
- RamDisk starts as boot-time driver
- XP boots from the RAM disk
XP preparation:
- Install XP on HD
- "Install" RamDisk as boot-time driver (patch registry and copy ramdisk.sys to \system32\drivers ramdisk.sys).

As I understood:
- Modified GRUB4DOS needs SYSLINUX installed
- euhenio's method works only with XP SP2 or 2003sp1 (probably because of "ramdisk(0)" in boot.ini)
- RamDisk driver starts as boot-driver in SCSI group (see his patch at the bottom)
- In boot INI he has ramdisk(0)\WINDOWS="MOBILEOS" /rdpath=\RAM.IMG /fastdetect /SOS /BOOTLOG
- euhenio uses "super-floppy" format (to be bootable on older BIOSes)

My notes:
- even compressed, image of the whole OS needs lots of memory
- reading of image via linux is generally faster then loading dlls via BIOS (as MS Win does)
- euhenio also mentioned "unbinding from iron" [to make it portable], as I understand, that's what MedEvil is working on.
- it's unclear how he managed to tell NTLDR how to read from RamDisk before its driver is loaded (did I missed something from 911 forum?)

PS
Special boot loader can be easily written to read the image into memory via BIOS (without any linux stuff).
I may find time to do that if you tell me "how to tell NTLDR..." (see my note above).

HOW TO boot Win2k3/WinXP in RAM

1. nLite your win2k3/winxp distrib to get it smaller. It's important if you don't have too much RAM.
2. Install nLited win2k3/winxp. I have installed it into VMware, but it bettter to install it on real hardware because if you use VMware installation on real PC you can get a lot of troubles with drivers.
3. Turn off pagefile in installed OS and hibernate and delete pagefile.sys.
4. Now look at hard disk properties to know how much space we need on ramdisk.
5. Making RAMdisk. You need qemu-img from qemu package.
run "qemu-img.exe create -f raw "win2k3.img" 50Mb" (change 50Mb to size that you want to see on your ramdisk)
now mount win2k3.img with Filedisk and format it with NTFS. don't forget to check Use NTFS compression if you want to save some memory and disk space.
6. Copy all files from disk that you have installed nLited winXp/win2k3 to formatted ramdisk.
7. Copy ramdisk.sys from Win2k3 SP1 CD into RAMDISK:\Windows\system32\drivers
8. Now run the regedit.exe and select HKEY_LOCAL_MACHINE and go to File -> Load registry hive and choice RAMDISK:\Windows\system32\config\SYSTEM hive. when you asked for name of hive type "sys". Next add

CODE

[HKEY_LOCAL_MACHINE\sys\ControlSet001\Services\Ramdisk]
"Type"=dword:00000001
"Start"=dword:00000000
"ErrorControl"=dword:00000001
"ImagePath"=hex(2):73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,44,00,\
  52,00,49,00,56,00,45,00,52,00,53,00,5c,00,72,00,61,00,6d,00,64,00,69,00,73,
\
  00,6b,00,2e,00,73,00,79,00,73,00,00,00
"DisplayName"="Windows RAM Disk Driver"
"Group"="SCSI Class"

[-HKEY_LOCAL_MACHINE\sys\MountedDevices]

[HKEY_LOCAL_MACHINE\sys\ControlSet001\Control\Session Manager]
"BootExecute"=hex(7):00,00

[HKEY_LOCAL_MACHINE\sys\ControlSet001\Control\Session Manager\Memory Management]
"PagingFiles"=hex(7):00,00

to your registry.
select HKEY_LOCAL_MACHINE\sys and go to File -> Unload Registry hive
9. Now you can unmount win2k3.img with filedisk
10. Put NTLDR from win2k3 sp1 disk into C:\ (replace existing one)
Add this line to c:\boot.ini

CODE

ramdisk(0)\WINDOWS="MOBILEOS" /rdpath=\win2k3.img /fastdetect /SOS /BOOTLOG

11. That's all. Now You can try to reboot and boot-up into MOBILEOS
P.S. What is your opinion about my English?

[Alexei]

P.S. What is your opinion about my English?

It's understandable, at least it's better then euhenio's russian, really
Just some minor stuff (friendly notes):
1. "if you don't " -> "in case you don't"
2. "but it bettter" -> "but it's better"
3. "Turn off pagefile in installed OS and hibernate and delete pagefile.sys." ->"In the installed OS turn off pagefile and hibernation, delete pagefile.sys"
4. "to know how" -> "to see how"
6."disk that you have" -> "disk where you have" or "disk on which you have"
8. "choice" -> "choose"
"asked for name of hive" -> "asked for the name of the hive"
10. "Put NTLDR"->"Copy NTLDR" or "Place NTLDR"
11. "Now You" -> "Now you"

Ok, I think that with this translation one can start getting the hang of it.

Thanks.


About step #5:

5. Making RAMdisk. You need qemu-img from qemu package.
run "qemu-img.exe create -f raw "win2k3.img" 50Mb" (change 50Mb to size that you want to see on your ramdisk)
now mount win2k3.img with Filedisk and format it with NTFS. don't forget to check Use NTFS compression if you want to save some memory and disk space.

There are some alternate methods, like using:
Winimage
DSFOK + VDK
MKDOSFS.EXE+VDK
