Probably fine. Fujitsu liked to be cute and put the files that actually touch the bios inside their custom compressed .arc files. DMI_LIF.com just calls the decompression program (loadarch.exe I think) and extracts the files to a RAM drive. It then loads a batch menu if I remember correctly.
finally, I run manually loadarch.exe to execute DMI_LIF.ARC and it gives me several options: 1) Show DMI settings 2) Write DMI settings with SN 3) Write DMI settings without SN 4) Show System Informations 2) Check SLP2 string But there is no option to add SLP2. I tried to add DMI settings, but it didn't help - SLP2 didn't occur.
