Quote from: Prodatron on 17:26, 15 March 16Really cool video!With FAT12/FAT16 you always start searching for a free cluster at the beginning of the FAT table. Problem with such special sectors (like #ff in your case) is, that it wouldn't meet the FAT standard anymore.Let's say iMPdos is later used with a normal SYMBiFACE II as well. Here you may have completely different data storages connected (like small CF cards, harddiscs with different sizes etc.). You may want to read/write them at a PC as well. Having a static special sector like #FF for storing non-FAT-standard information could cause problems with the filesystem integrity then, and you don't know if sector #FF is already used for storing the FAT/files/directories on other storages, so maybe you even destroy something.If you want to speed-up the cluster search, I would recommend to store the number of the first free cluster in ram. So when doing a search for the first time after you switched on the computer you have to walk through the whole FAT once, but after this you can use the cluster number stored in memory.

Quote from: Joseman on 19:51, 15 March 16We want IMPdos compatible with our symbiface II !!
Quote from: TFM on 20:20, 15 March 16Yes, it would be great to be able to use SF2 and FAT file system in the native OS (12 years after the release of the hardware) eventually.

Quote from: Singaja on 19:35, 15 March 16Couldn't the number be stored as a file or kinda "reused" 4 byte Volume Serial Number?FAT Partition Boot Sector
Quote from: Ast on 22:36, 15 March 16Finding the first free cluster is not a problem, iMPdos already does it!
Quote from: Singaja on 20:47, 16 March 16I did a test with edited Fat16 partition on Windows 8.1With oem name/version: CPC6128 and 0x0 padding in greenand volume serial set to OWNZ (actually the number as a serial is read as big endian).Windows didn't complain and the partition is fully useable
Quote from: CraigsBar on 20:51, 16 March 16So is impdos a replacement for acmedos? Is acmedos shelved? Or are we in the crazy situation of having 2 close to completion amsdos fat32 drivers? Am I the only one confused?
