The BitMap data are extracted from a BMP file I saved in 640*480 256 color , it's why the picture is up side down. INIT_DISPLAY setas ; diable the border LDA #0 STA BORDER_CTRL_REG ; enable graphics hardware and...

Hi, I'm trying to display a bit map of 640*480, I have the data loaded from 0xB1:000 up to B4:B000 (640*480 => 0x4B000). The issue I have is that the screen don't look fine at all.

Re: FAT 32

Small update for the fat : it's working(ish). I can search for a file in the root directory (first folder of the absorbance like C:\ or G:\) and if the name match (short name : 8.3 exactly) well it load the first cluster of 512 Byte on the screen. http://image.noelshack.com/fichiers/2019/38/7/156917...

Re: FAT 32

It is great work, but I'm not sure you should remove the ch376 (and I am not saying that because I was working to implement it in de IDE :), things change). The ch376 is a somewhat low threshold chip, "easy" to get going and if people want to do stuff or experiments without the standard kernel, it ...

Re: FAT 32

Small update before going to bet. I can now read the directory entry to search for a file or folder name. I also coded/debugged the function to look in the fat to get he next data cluster if you give him the current cluster. http://image.noelshack.com/fichiers/2019/37/3/1568160683-fat32-root-folder-...

Re: FAT 32

So far I can read the MBR, the Boot Sector, and the Root Directory with the first data cluster associated with the file/folder Now I need to test the FAT function to get the next cluster from the current cluster. The 5E in the picture mean : deleted file. http://image.noelshack.com/fichiers/2019/37/...
