Problems with PowerMac 7500
I just got some new memory for my 7500 today. It was EDO RAM. While is is 168pin, the notches are different. I trimmed the notches to fit(DO NOT TRY THIS if you aren't an expert, it can damage your computer) since the 7500 is supposed to be able to use EDO RAM. Mac OS 9.1 booted with no problems and the system was very snappy(from 80MBs). However, when I rebooted into Linux with BootX, the Adaptec card reported an error reading my Linux Drive. After some experimenting, it seems that NONE of my PCI card will work properly now expect my ATI video card that has a MAC ROM on it. I have seen EDO RAM used with the 7500 before, and I have tried other EDO RAM chips and have the same problem. Does anyone know why this is and how to fix it? If it means that the RAM won't work, that's fine. However, it is just really weird that the MAC OS is fine where Linux fails. When I replace the old memory, it works fine......Very weird. Any suggestions would be appreciated. Thanx __________________________________________________________________ Look What The New Netscape.com Can Do!

Larry, I think you've answered your own question with the last 2 or 3 sentences. If you are still unsure, run memcheck or memtest from your LILO screen. I think Linux may be quite a bit more sensitive to ram than your OS 9.1 is, because of the way ram is used by Linux. I suspect you would find the same problems with OS 10, if you were running it. Lee
