I have GVP in that A2000 with a GVP 040 and 32MB of ram plus an Indivision ECS; I keep the OS on the CF and the WHDLoads on SD. It has a dual boot ROM so I can degrade it back to KS 1.3 and a 68000 if I need to. I use my other SCSI CF readers in my A4000T's where they work fine, except I can't boot from them in OS 4.1; I can boot from a CF over my IDE Controller (scsi.device). But we are here to answer why the controller flashes every second, which we did; so on to new thread!
