Hi Thanh, I had the same problem on the my redHat 6.1 system. Look in the /etc/lilo.conf file. Mine looks like this: <-- Top of File--> boot=/dev/hda map=/boot/map install=/boot/boot.b prompt timeout=50 default=linux vga=extended image=/boot/vmlinuz-2.2.12-20 label=linux initrd=/boot/initrd-2.2.12-20.img read-only root=/dev/hda5 append="mem=128M" <-- End of file --> You must be logged as root to change this. After you make this change the run LILO as root. "/sbin/lilo" Later, Robert Wynkoop -- 77 FireBird See at http://www.inlink.com/~rwynkoop/77bird.htm -- ----------------------------------------------- - Application development: VB60, JAVA, C++ - - PC client support - ----------------------------------------------- [All my opinions are just that, my opinions, and do not reflect the opinions of my employer] Mail: [EMAIL PROTECTED] [EMAIL PROTECTED] [Original post] Hi everybody, I'm having a problem with RAM upgrade and I don't know how to fix it either who I can ask, so really apologize for this question. I had 64 MB RAM and I've bought 64 MB RAM. The problem is that BIOS and Windows see the new RAM but Linux not. Any help would be very appreciated, thanks! Loan.
