Not regarding how useful it is, yes, it works. The Sys-Check diagnostic firmware disables the U1MB BIOS and features (as possible), so you might run the RAM test also having an U1MB installed. The other features (external O.S. switcher and/or external 512 KB RAM expansion) works also, but... the U1MB does it already 🙂 2 1 Quote Link to comment Share on other sites More sharing options...
