Unfortunately, the error messages I get still suggests that the EEPROM is still write protected. A 'DIR/W' command reveals a bunch of files with the two most interesting for my purposes are 'SERUPDT.EXE' and 'SERUPDT2.EXE', both of which have reasonably clear instructions for updating system EEPROM data. However, the 'COMMAND.COM' supplied with HMD is only 9kb, while the 'COMMAND.COM' supplied with Rufus is 90kb? If I copy over Rufus' COMMAND.COM the AUTOEXEC.BAT fix 'works' but it boots to a C: prompt. Howeever, when I do, it boots straight into the utility. I have to manually enter the path to 'COMMAND.COM' which is right in the root directory and shouldn't be necessary. That's usually a problem with the MS-DOS 'PATH' command in 'AUTOEXEC.BAT', but 'fixing it' has no effect. If you make it with Rufus it's bootable but when it boots, it can't find ''. Here I thought that replacing the mobo was going to be the hard part! Do you hit 'esc' one time or multiple times or do you hold it down continously? The following is going to really date me: As you probably know, making a bootable usb with the utility provided with the HMD doesn't work it isn't bootable. What's supposed to happen when I press escape anyway? And what's IBM/Lenovo trying to accomplish by making what should be routine so difficult? Pressing escape while the Lenovo logo wes showing had no effect, and when I disabled quick boot and enabled diagnostic boot the Lenovo logo went away altogether. However, I can't seem to get around the EEPROM write protect error. It must be easier to find the current nuclear launch codes! With that out of the way, I was able to find version 1.83 and, with Rufus, (thanks for that too) create a bootable usb drive to with which I made the invalid uuid go away. I'd rather fix it if possible.Īny guidance will be appreciated. Are there truly no copies of this software anywhere? I can live with it as long as it boots, but it is worrying. My research suggests that a it is possible to 'Fix' this issue with software that's only obtainable by Lenovo field techs. 2201: Machine UUID is Invalid After that, it goes on to boot 'normally'. I just replaced the motherboard on my W510 and now when it boots up I get the following errors: 2200: Machine Type Invalid and Serial Number are invalid. 2200: Machine Type and Serial Number are invalid.
