Re: Unable to boot from USBdevice

Hi all,

the message through boot

NTLDR: Bad boot.ini found

belongs to the i875 chipset AND the
HP format utility. This message is gone if you use the FAT16 from XP.
You will have no luck if you try to boot from
USB with OHCI USB driver (SIS Chipset) because there is no entry in the
CriticalDeviceDatabase for it.
Also there is no entry for booting from USB 1.1.

For those people, add (doubleclick) the following to the registry of your
USB bootdevice
BEFORE FBA name it Critica.reg in system AND system.sav

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase]


[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#cc_0c0300]
"ClassGUID"="{36FC9E60-C465-11CF-8056-444553540000}"
"Service"="usbuhci"


[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#cc_0c0310]
"ClassGUID"="{36FC9E60-C465-11CF-8056-444553540000}"
"Service"="usbohci"



And also you have to add named serv.reg


Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\USBUHCI]
"Start"=dword:00000000
"Type"=dword:00000001
"ErrorControl"=dword:00000001
"ImagePath"=hex(2):73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,64,00,\

72,00,69,00,76,00,65,00,72,00,73,00,5c,00,55,00,53,00,42,00,55,00,48,00,43,\
00,49,00,2e,00,53,00,59,00,53,00,00,00
"Group"="Base"
"DisplayName"="USB 2.0 Bus Driver"
"Description"="USB 2.0 Bus Driver"


[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\USBOHCI]
"Start"=dword:00000000
"Type"=dword:00000001
"ErrorControl"=dword:00000001
"ImagePath"=hex(2):73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,64,00,\

72,00,69,00,76,00,65,00,72,00,73,00,5c,00,55,00,53,00,42,00,4f,00,48,00,43,\
00,49,00,2e,00,53,00,59,00,53,00,00,00
"Group"="Base"
"DisplayName"="USB 2.0 Bus Driver"
"Description"="USB 2.0 Bus Driver"



After that, copy the drivers usbohci.sys and
usbuhci.sys to windows\system32\drivers.

Good luck
Dietmar
