Hello, I'm new to this forum even though I have read many topics so far. I just bought an used Toshiba Portege R600 and the seller installed XP in this laptop and he forgot to make the Recovery Disk before. Now, all has been gone, even the recovery partition. I tried to install Windows Vista, but I can't get it actived, cause of the oemcert. I have tried 4 oemcert of Toshiba that I found but none of them works. Here is the SLIC infomation: Memory address: B6797692h Table length: 374 OEM ID: TOSHIB OEM Table ID: A006A Creator ID: TASM I'm looking for the right oemcert. Thank for your help
