Hello All,
Anyone can inform me what's the largest Compact Flash card that is supported under Sunrise IDE? I dont want to buy a 4gb one and find out that the maximum supported is 512mb!
Best Regards,

hbarcellos: I assume the maximum size is the same as with the normal IDE interface: 8GB. You can insert larger disks, but only 8GB will be visible. FAT16 restricts maximum partition size to 2GB, using FAT12 you will be able to address a maximum of 32MB on a partition. The IDE interface supports up to (if I recall correctly) 31 partitions. Might be one more or less, but it's more than enough anyways.
I myself have a bunch of FAT12 partitions which I mainly use for boot, work, tools, etc. Furthermore, I have 2 FAT16 partitions for backup, games, music and the like.
Note: this is on a 4.3GB Western Digital IDE hard disk.

Now I'm confused. If the maximum is 31 partition (~), how can NapalM have 992 partitions?
and, whats the maximum size for fat 16 partitions? I know that fat12 is 32mb, but what about fat16?

You assign drive letters to any partition. As D-Tail said, 2GB is the max size of a FAT16 partition.
NapalM said that he has 2 partitions: 1 of 32MB (FAT12) and one of 992MB (FAT16).

Note that it might be wiser to choose your partition sizes somewhat smaller: as the size of a partition increases, so does its cluster size. If I'm right at 2GB for a FAT16 partition, the cluster size will be around 32kB. Which means that a file of 1 byte actually gets blown up a 32-thousandfold. At 32MB for a FAT12 partition, it's the same thing.

Anyone tried the DOS2 that comes with OCM with the sunrise device? It might be able to handle a straight FAT16 format ?

To avoid confusion , that 512 mb is de flashrom and has nothing to do with the capacity of the flashcard you gonna use and is indeed 8GB , IF YOU WANT to keep your diskdrive(s) |

Um, isn't the flashROM 512kB? (not mb.) Anyway, it's clear.
8GB! |

Why should 8GB be the maximum? Because of 4x2GB FAT16 partitions?
In general there is not such a limitation on hardware side. I use a 16GB CF card (formatted in FAT32) on my MSX without any problems.
