Guys, sorry for asking, but what is  about any progress over here?
I could perform some test in BartPE environment if it is necessary.

As far as I understand this is not the pure problem in Bartpe...

Respectfully, Viktor.

I use SP3.

Additional info:

If I get rid of megasr completely in txtsetup.sif - all working fine, but if I have at least one hwid refer to megasr in txtsetup.sif  it is the same above mentioned situation.

Hwid :
PCI\VEN_8086&DEV_27C3&SUBSYS_107A147B&REV_01
PCI\VEN_8086&DEV_27C3&SUBSYS_107A147B
PCI\VEN_8086&DEV_27C3&CC_010400
PCI\VEN_8086&DEV_27C3&CC_0104

Compatible Ids:
PCI\VEN_8086&DEV_27C3&REV_01
PCI\VEN_8086&DEV_27C3
PCI\VEN_8086&CC_010400
PCI\VEN_8086&CC_0104
PCI\VEN_8086
PCI\CC_010400
PCI\CC_0104


- it is from the installed windows xp sp3 on this comp.

The Volume is not visual at all.

Thanks in advance

I have AW9D MB with ICH7R/DH raid ( default driver iastor78.sys). When I boot in with UBCD4WIN with mass storage DP 9.01, the system pickup the driver megasr.sys as I see in registry HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 4 : Driver : megasr and take a dummy volume device from megasr.inf instead of my Raid Volume. Could you Help Please?
