Hi,<BR>
<BR>
Thank you for your such a detailed help decryption, but the problem I still can't resolved.<BR>
Here is a very simple way to reproduce, 100% happen.<BR>
When I boot from standard gpxe rom, undionly.kpxe, which is hold in a tftp server, and then press Ctrl+B enter command line:<BR>
type:<BR>
dhcp net0<BR>
sanboot iscsi:myip::::myiqn (I see your website said sanboot iscsi:myip::::myiqn:iscsiboot, but I can't use :iscsiboot, gpxe response a invalid parameters)<BR>
<BR>
it response:<BR>
Registered as BIOS drive 0x80<BR>Booting from BIOS drive 0x80<BR>Boot failed<BR>Unregistering BIOS drive 0x80<BR>
<BR>
The disk which this iqn has no MBR, so the will boot fail (just for test).<BR><BR>
Then I type exit to exit gpxe command line, it will boot from my harddrive, after booted, I opened computer management console, I can't see a hard disk (only on local hard disk).<BR>
<BR>
I've also tried set keep-san 1, it is the same thing.<BR>
So I think there may be a problem in int13, is that replace the original int13 drive? if yes, how can I prevent it replace the original int13 drive?<BR>
<BR>
Best Regards,<BR>
Aldrich.<BR>

I would expect no LowerFilters (or maybe hpdiskflt) and one UpperFilters: PartMgr<BR>> - You could delete all values inside the HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\ Registry key and reboot<BR>> - You could right-click the disk device in Device Manager, choose Properties, click the Volumes tab, then click the Populate button and report what shows up<BR>> - You could use the 'mountvol' command and report what shows up<BR>> - You could download BeebleBroxNT[1] partition editor and report the exact details it shows<BR>> - You could inspect the Registry key at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\dmadmin\Parameters\ and report what you find there<BR>> - You could use 'diskpart' and then 'list disk' and 'list volume' and report the detail<BR>> <BR>> Hope this helps.<BR>> <BR>> - Shao Miller<BR>> <BR>> [1] http://sourceforge.net/projects/beeblebrox/files/beeblebrox-windows/0.0.2/beeblebrox-0.0.2-win.zip/download<BR>> <BR>> ________________________________________<BR>> From: KernSafe Technology [mailto:kernsafe@hotmail.com] <BR>> Sent: Monday, May 10, 2010 07:28<BR>> To: Miller, Shao<BR>> Cc: gpxe@etherboot.org<BR>> Subject: RE: [gPXE] Why disk not appear in the disk management tool?<BR>> <BR>> Hi,<BR>> <BR>> Thank you for your help.<BR>> The guide is following gpxe website mentioned previously.<BR>> Boot progress:<BR>> 1, dhcp, Router and My own bootp service<BR>> 2, tftp, third part standard ftfp server.<BR>> 3, gpxe, use the standard and complied undionly.kpxe<BR>> 4, iscsi, used a few type of targets and initiators, are all the same.<BR>> 5, sanbootconf, download from etherboot.org<BR>> <BR>> the iSCSI targets and initiators I have tested to change other brands (includes microsoft initiator), the problem persist, so I think it is irrelevant to the iSCSI.<BR>> The disk parition, I'm sure they are not the same, and even just one disk, it have the problem.<BR>> Did other things will cause the problem? bootp or sanbootconf?<BR>> <BR>> > Subject: RE: [gPXE] Why disk not appear in the disk management tool?<BR>> > Date: Sun, 9 May 2010 11:33:35 -0400<BR>> > From: Shao.Miller@yrdsb.edu.on.ca<BR>> > To: kernsafe@hotmail.com<BR>> > CC: gpxe@etherboot.org<BR>> > <BR>> > Sorry, Aldrich, I mis-spelled your name on this Apple MacBook keyboard,<BR>> > which often misses keystrokes.
