Hi.
Thanks you all developers that workd on Grub. With grub and the Badram and Memmap command i was able to fix my Laptop with bad/broken soldered ram memory in the motherboard.
Actually "memmap" was the one that worked, which reserved specific memory address making the OS bootable and stable.
The catch was to install linux on a good working PC and edit the cfg /etc/default/grub to include some specific memmap lines for the memory addresses that needed to be blocked, then transfer the hard drive to the broken memory laptop. This fixed everything. and the laptop has been running perfectly.
I have not found a way, and there is no information online, if this is possible to do with a LIVE linux USB flash drive. As soon as you boot from a live USB flashdrive, the machine starts to use bad broken soldered memory. And i wish there was a way to edit the live usb boot flash drive so it has edited GRUB memmap commands in order to boot with the USB live linux and blocking that memory address.
I have read i should prepare the live-usb flashdrive with rufus, but the files are completely different from what you do with a linux that is already installed on a hard drive and changing
/etc/default/grub cfg
If this can be done in the future it would really help, to most of us that have bad soldered memory on the motherboard. Would be nice to live boot a linux and block some memory addresses.
thanks!
