[Staffslug] ACPI question :-)

I've got Xubuntu running on an oldish PC. I have to say I am really enjoying the experience. However, I have a question for the team... As the PC is booting I get a message flag up about the BIOS being past the cut date for 2000 (what cutoff?) and I 'apparently' need to do ACPI=force. Ok, I can do that...but where? Is this in a GRUB file somewhere? Is it likely to be just hashed out or will I need to type it in? If the latter is there a specific line that it needs to be entered on for it to take effect? -- ============================================== Kevan Farmer Linux user #373362 Staffordshire
