This actually sounds like a manifestation of bad 1400 RAM voodoo. The 1400 seems to have some issue about how many "modules" it can have installed at a given time. In my case, mine started as a 117MHz. This has the 4MB "Apple" module, and it came with 8MB in the stackable slot. This works. I then upgraded the 4MB "Apple" module to an 8MB pull from a 133. This works. I then bought a 48MB stackable module to bring it right to 64MB. Got the same error you did. Scratched my head, called the company. Replacement did the same thing. In desperation I started pulling and replacing RAM. Eventually yanked the 8MB "Apple" module and it gave me 56MB instead of 8. Scratched my head and put back in the original 4MB module. 60MB. Put in the 8MB module again. Scream and whine. For whatever reason, especially in the 1400s that didn't come with 8MB "Apple" modules stock, there seems to be some limitation on how modules can be installed together. In my case, I had to downgrade to a 4MB "Apple" module to get at least 60MB seen all told. Others have seen this kind of funky mojo, so it's not just something freaky with my 1400. -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.
