Great thread. Does this cmos battery need to be resoldered after removal? My old 386 had one like that! They didn't miss too much when they crippled it. I still have 10 pages to read before flashing my 2.07 bios.
I bought one there too. Did you try the update http://www.poweredbymushkin.com/index.php/support/ssd-firmware-updates.html ? I haven't installed mine yet but may get their Flux enclosure and buy a bigger one.
I believe that you may be referring to https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Disk-Partioning-and-OneKey-Recovery-Feature/td-p/8034/page/40 Take a look at this for reference to ptedit32 by Symantec.
