for windows, we can see the "system model" string value through "all programs->accessories->system tools->system information". And I think it is related to bios. As already knows, the EsxBiosTools can extract the rom file from ESX and inject the rom file back after modifying it by tools like Phoenix BIOS editor . However, it seems that these tools can only modify the string value which can be viewed in the bios setup. Unfortunately, the "system model" string is not list there. So, is there any way to modify a VM's "system model"? Much appreciate for your help
