What does your grub entry look like now?
Hmmm...OK let's start fresh. Where are you booting from, hard drive frugal install? Did you install Grub4DOS? If so, where you installed Grub4DOS, open the menu.lst file and look for the Tahr entry and copy and paste that here so can see what you have.number77 wrote:Sorry to show my ignorance but how do I access the kernel boot line in grub.
Just add it to the end of the kernel line like I did above.number77 wrote:Frugal instal to hdd

I would interpret this as indicating that the lockup/hang is not caused by the hardware sensing the loss of AC. I would interpret this as suggesting that it is the Linux software code itself that is generating a signal when the AC drops, and this signal is causing the problem.number77 wrote:I can disconnect psu and it sits there saying boot: pfix=ram.
