FiraDisk (latest = 0.0.1.30)

Thanks Karyonix,so I use the VHD image file as is,because there is only a warning message,it is able to boot without problems.
Since I installed Windows XP on the root of the USB disk,I load Windows 7 into memory using the XP boot procedure and GRUB4DOS. How can I boot Windows 7 from the VHD image file using them ?

boot.ini

[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 FLP" /noexecute=optin /fastdetect
c:\grldr="Grub4Dos"

menu.lst

title Boot 7 from RAMDisk
find --set-root /7-ram_2_6G.vhd
map --mem /7-ram_2_6G.vhd (hd0)
map --hook
root (hd0,0)
chainloader /bootmgr

is this correct to add something like this to menu.lst ?

title Boot 7 from VHD
map (hd0,0)/7-ram_2_6G.vhd (hd0)
map (hd0)
map --hook
chainloader /bootmgr
or
chainloader (hd0,0)+1

title Boot 7 from VHD
map (hd0,0)/7-ram_2_6G.vhd (hd0)
map (hd0) (hd1)
map --hook
chainloader /bootmgr

Windows 7 boots,but after few seconds : BSOD ; STOP : 0x0000007b

title Boot 7 from VHD
map (hd0,0)/7-ram_2_6G.vhd (hd0)
map (hd0)
map --hook
chainloader /bootmgr

gives this error :

map (hd0)

error 11 : unrecognized device string or you omitted the required DEVICE part which should lead the filename.

http://diddy.boot-la...s/files/map.htm

Map command expects FROM and TO. You have FROM, where is TO? Where do you map HD0 to? What's actually your idea about this line, what are you trying to accomplish?

---> map (hd0) (hd1) ---> BSOD ; STOP : 0x0000007b

hd0 because I want to load Windows 7 from the VHD image file and it is always mapped on (hd0)
hd1 because 7-ram_2_6G.vhd is located on (hd1)

is this right ?

but why I get 0x0000007b ?

The VHD file should be launched from BOOTMGR Menu instead of from Grub4dos Menu.

Make an entry for VHD file in BCD store of Windows 7 using bcdedit.exe and then boot from BOOTMGR Menu

Boot with bootmgr of Windows 7 first into BCD - BOOTMGR Menu and then boot with Win7 VHD-file

Forgive me if discussed already...

I have a working livexp build (no log errors) with firadisk bootsdi using 077rc2 but some issues and questions remain. There appears in my computer a virtual drive
 fira_imgburn_virdrverr2.jpg   25.42KB   15 downloads
that is not recognized by imgburn.
 fira_imgburn_virdrverr.jpg   14.49KB   6 downloads
Why is this virtual drive present (what purpose is served)? Can I change a setting to avoid its creation? If this is a known issue, is there a fix in the works? etc. etc.

btw, thanks again for the firadisk driver!

@amalux

I feel for tests you boot the iso image with somethings like that

title LiveXP_RAM.iso - mem

find --set-root /LIVEXP_RAM.ISO

map --mem /LIVEXP_RAM.ISO (hd32)

map --hook

chainloader (hd32)

If this is true:

I don't know the technical explanation, as far as i know windows can't understand grub4dos image mapping but aware there is a device, as a result there happens drive letter.
Same think also happens when M$ ramdisk.sys used.

@karyonix
probably you already know, better to remind not to cause misunderstandings, bootsdi on livexp have a wrong naming, it is not sdi, it creates an image with oriensol's hddimage (default) or superfloppy and does the rest.

btw, I love your explanations (posts), they are very clear and straight, current topic is also an education topic for me

Lancelot,

Sorry, meant to mention it, yes, booting from ISO (my preferred way for testing). IMA bootsdi doesn't have this issue, I guess I'll go back to that for now

(my preferred way for testing).

With having firadisk now, time to change old habits of ramdisk.sys , single bootsdi.img (with firadisk) is enough for booting
Besides, my favorite test method for a while is using LiveXP.iso with firadisk + grub4dos

Hurrraaaa firadisk Thanks a loooot karyonix

I guess you're saying there's a way to boot from firadisk bootsdi ISO without causing this virtual drive issue?! Nice -- I'll check out your post

Beautiful

find --set-root /LIVEXP_RAM.ISO
map /LIVEXP_RAM.ISO (hd32)
map --hook
chainloader (hd32)

Thanks again

The topic about conversion from .img and .vhd has been moved here:
http://www.boot-land...?showtopic=9715

Hi karyonix,

nice work !

I take a look about the speed of XP in Ram.
I have a complete XP SP1 on CD, and put this to ram and boot.
Boottime because of slow CD is 2 min.
I use for this the ramdisk.sys driver 5.2.3790.1830 from Microsoft.
The size with this is limited to 500 MB.
The NTFS compressed image on CD has a size of 497 MB.
It boots all computer, that I have .
But write speed in ram from C: is only 40 Mbyte/sec
and read 200 Mbyte /sec. Exact the same behavior shows the XP in ram with the driver from diskless angel.
When I do USB boot and use EWF Ram from Windows Embedded,
I get 1000 Mbyte/s read speed and 500 MByte/s for write.
A normal ramdisk xp pro from Superspeed software shows 1400 Mbyte/s read and 1000 Mbyte/s write speed.
As mentioned here in the forum, this is because it uses direct memory access DMA. My own driver for ramboot ntbootdd.sys uses the scsiminiport driver model. To allow direct DMA operation you have to use in the ramboot driver

Windows Driver Kit: Storage Devices
ScsiPortGetPhysicalAddress
The ScsiPortGetPhysicalAddress routine converts a given virtual address range to a physical address range for a DMA operation.

SCSI_PHYSICAL_ADDRESS ScsiPortGetPhysicalAddress( IN PVOID HwDeviceExtension, IN PSCSI_REQUEST_BLOCK Srb OPTIONAL, IN PVOID VirtualAddress, OUT ULONG *Length );


Nice to hear from you all,
Dietmar

Hi Dietmar,

MS ramdisk.sys driver is working with images above 512 MB (guess limit is almost 4GB) with patched ntldr

http://www.boot-land...?showtopic=9474

actually wanted to ask you, why preferring XP SP1?

@Dietmar
I don't think DMA is that fast.
I still don't know exactly what causes slow read/write.
Maybe better queuing or scatter/gather list can improve RAM disk read/write speed.

Hi karyonix,

if I interpreted

http://download.micr...eb/Storport.doc

right, then should be with 50% CPU use 1,79 Gbyte/sec possible with DMA at a package size of 512 byte. I am quite sure about this, because also PCI-E uses DMA,
nice to hear from you
Dietmar

If you use DMA to transfer data CPU usage should not be more than few percent.
I don't know the maximum speed of DMA and how to use DMA to copy data from RAM to RAM.

Hi karyonix,
I just looked with IDA dissassmbler at your file for ramboot .
I noticed, that you do not use the scsiport model for your driver. Even diskless angel does not use it. But I do it for my ntbootdd.sys. So, for me it is easy, to do very small changes to my driver to get full DMA access. I also noticed, that the ataboot.sys driver from Microsoft, renamed to ntbootdd.sys works nearly exact as my driver. Even for USB boot it looks not so difficult to use my ntbootdd.sys with only very small changes. I make a try with my ntbootdd.sys for ramboot with DMA and show you the speed results.
My problem is "only" to get enough free time for this,

If I may , your problem is failing to provide your ntbootdd.sys , I really don't get it:

• you do not release it
• you do not give it's code
• every, say, 6 months you come back from nowhere, only to post a tantalizing hint about how good it is

Last time you ignored my question, if I am not mistaken:
http://www.911cd.net...o...20450&st=44

Or is it a conspiracy involving you and the abandoned FreddyV driver:
http://www.boot-land...?showtopic=3593
http://www.911cd.net...showtopic=20450
to try making me mad?

You are of course perfectly free to keep both the actual driver and its source for yourself , but this is teasing!

P.S.: since I know, and you know you are NOT coming from Afghanistan, you may want to read this:
http://www.boot-land...?showtopic=3153
and comply with it.

Hi jaclaz,
you are right. My problem is always small time :-),
nothing bad at all. I cant upload my ntbootdd.sys here.
I get a message "Upload failed. The file was larger than the available space" even it needs only 32 kbyte spave.

You only need to put to a higher hex number, for that this works for more ram, this is for exact 32 Mbyte

const ULONG DiskBase = 0x2000000;

I think, 2 Gbyte are possible (Fat16).
The USB ntbootdd.sys from Freddy, that you give to me, uses nearly the same but with direct DMA support.
This ntbootdd.sys starts any XP or whatever, that you put to ram! I put it to ram from USB, CD, DVD, harddisk.
Harddisk needs only 1 sec to put to ram and start 32 MByte XP from there!
The size of the ramdisk has to be exact the same as Diskbase.
It works as the following: You put XP (or any other) to ram. You need to know exact, where this XP stays in ram! Then you do warm reboot.The XP content in the ram survives this. This ntbootdd.sys shows after this part of the ram as harddisk and it boots to XP from there in 1 sec!

Here is the cpp Source code ntbootdd.cpp with little modification (thanks
to Gary Nebbett 1997)for ntbootdd.sys . I compiled it for NT4 and for XP
and it works. If You change scsi.h against storport.h it doesnt work any
more. The compiled size is only 3kByte. It is not too difficult, to
understand, how this program works. I also give you my SOURCE file for
compiling, because these libraries are NOT includet by the compiler
himself. That is, what I call a nice program, not MEGA and MEGABYTE from
people, who dont know how to make it better...

Strange.

Maybe you need to logoff and re-log on , I just updated your "storage" capacity on boot-land.

@Dietmar
The driver compiled from your source code with Windows 2000 build environment of Windows Driver Kit SP1 for Windows Server 2008/Vista.
I renamed it and changed sources file to match my build environment.

I read your source code. The driver doesn't use DMA. It uses memcpy to copy data.
From your source code I learned that ScsiPortGetDeviceBase can be used instead of MmMapIoSpace to map physical memory address to virtual address. It will be very helpful when I write a SCSI miniport driver. Thanks.

v0.0.1.16 : RAM Disk speed improvement
Enabling cache and using __movsq or __movsd instead of RtlCopyMemory result in faster transfer speed than previous versions.
