Hi Jean, 100% Agree, I wanted to write that too but have no time :/ Btw david. You can set the HEFRAS bit in CR26 to move your superio to 0x4e/4f. (write 0x40 to 0x26 + key) I tried that and now I got same err ... Ending clean XFS mount for filesystem: dm-2 w83627ehf: unsupported chip ID: 0xffff ruik:/home/ruik# I think test for 0xffff should be there. I think ISA decodes empty spaces as 0xff. Rudolf
