I haVe a Thinkpad 600. I am trying to install eCS 1.1 onto it. I replaced the hard drive. It checks okay with the cmos test. I boot using disc one of eCS 1.1. It does not show any errors. It does not get any farther than the eCS ball. It has 233 mhz Pentium 2, 163 mgabyte of ram, a 5 gigabyte hard drive. Sometimes the screen goes blank and I have to unplug it and take out the battery before it reboots and shows anything on the screen. I have heard that others have installed eCS on a 600. Any help would be appreciated.
