Something just popped into my head after having a troublesome WarpUP installation last night. Does OS3.9 first time installation (when you install the OS from scratch) secretly put ppc.library in LIBS: directory if it detects a CSPPC accelerator? I know that CSPPC doesn't have ppc.library in boot-rom as BPPC does, however I had trouble installing WarpUP on my A4K with CSPPC last night (it would crash right on boot when it looks like it's just about done loading workbench), much in the same fashion as it does on a BPPC A1200 setup with no BPPCFix installed to disable the rom built-in ppc.library (I've had this setup before so I remember). I will look into LIBS: for a ppc.library file when I get back home from work (just in case it is actually there), but if I don't find it, what could actually be crashing WarpUP and the entire OS on boot?
I have an A4K rev B installed in Mirage 4000 Pro case with Mediator 4000 that came with it and Zorro/PCI busboard, CSPPC with 128MB Ram, No RAM on motherboard other than 2MB chip ram, Voodoo 3 PCI 3000, Terratec 512i, Ethernet card 10/100, FastATA 4000 Mk2, OS3.9-BB2, Blizkick running optimized for single-boot.
