Sandisk 8gb ultra recocnizes it sees all the partitions fron the boot menu but keeps on booting and the floppy drive clicks normaly. I used to be able to boot from all these cards in my amiga 600 and in winaue. The only working card is my old sandisk 512kb it boots ok but the space is too limited. Can you advise me to do something?
I have had problems with these brands of cards before on both several A600's and A1200's - they seem a little hit and miss, however SanDisk seem to be the Daddy in this area - with the exception of one older 64MB SanDisk CF Card - every SanDisk branded card I have tried works - and that includes A600/A1200 and the ZX Spectrum 128k +2

However in saying that I have had some booting issues, and to solve this I had to replace the capacitors - on two A600's and 3 A1200's - the Former most recently.

This is why they added an extra delay in KS 3.1, so you might have better luck if you change to KS 3.1 if you haven't already.
Timing is everything:
I think this is quite close to the nail for the hammer - I suspet that not all CF cards present themselves properly on the IDE Bus under PIO mode as they expect a UDMA protocol - of those that do, I suspect either a tight - strict adherence of IDE interface protocol - which may not be *wholly* present in the scsi.device or a loosely based PIO Mode IDE protocol that breaks compatibility - sadly I don't have any direct evidence only a lot of statistical tests that could possibly suggest this.

Whats the Expense:
Hmmm you would need an interface from the 68EC020 to the new 68040/60 - essentially another board - where in fact it would be cheaper to redesign one from scratch. Sadly obtaining enough 040 and or 060 CPU's that are known working and financially viable - as well to hold a warranty - is the limiting factor here.

Well it is, just massively impractical - one could argue (and rightly so) that its not mass market possible - so hence the success of the Vampire / Apollo '080 Core projects.
