Need help with A1200 booting problems

[SteveP22]

I am having troubles booting my Amiga 1200 (with Blizzard 1230 IV, and FastEIDE controller) Sometimes it will boot from my compact flash other times it sits at the load disk screen. Using the old laptop hard disk it does the same thing. I have tried three different CF adapters. The onboard ide does the same.

The Laptop hard drive is 2GB, the CF is 4GB with 2 2GB partitions. I am using a Amiga 500 power supply and an ATX for the CF and floppy until I can fully move the 1200 to be powered from the ATX.  Seems to be working now. The 1230 had EDO memory and when I remove the 1230, it boots and softkicks 3.1. With the memory it boots but softkicking fails. Dont know if this would cause it or not, or if this is another problem altogether.

The processor 68030RC not an EC. If I put the 1230 card without memory it softkicks but yellow screens.

The maprom jumper has been set open, and have also tried removing the jumper, still it gives the yellow screen. Have tried different memory too.

Tried setting it to chip ram, still get yellow screen

I connected the ATX to the 1200 fully now. I have ran ICD Mem Test on a few memory sticks and all fail towards the end of the memory address space for fast ram.
