No such string present

Guest Author: Oliver07 Feb 2018

I followed these steps on Mac using Hex Fiend and DAEMON Tools, and I burned the iso using Bootcamp. When I tried to install on an IBM R51, Thinkpad, it didn't work. It said 512mb ram not installed. I was using 256mb. Can you please tell me how to fix the error or send me a pre modified iso to my email?

Can you send me a video

I tried it and it did not work, wasted a DVD :( I had to download the RTM release to find the string specified, the newer versions don't have it, but it still didn't work

By the way, to edit the ISO don't use the suggested programs, they charge money. Download a program called Anyburn, the hex editor used in pictures is the one you want

But like I said, it still didn't work :( If anyone figures out how to make it work email me morejiggawatts at gmail com
