| A new feature implemented with runnix-0.3.3 and AstLinux 0.7.8 allows the AstLinux distribution to be placed on a USB flash drive and operate just as if it were on a CF card. | A new feature implemented with runnix-0.3.3 and AstLinux 0.7.8 allows the AstLinux distribution to be placed on a USB flash drive and operate just as if it were on a CF card. |
| For the case where the AstLinux system box cannot boot directly to a USB drive, there is a solution for that, by using the CF card to "boot" the USB flash drive, "CF + USB Combo Booting". Follow steps #1 through #4 below. | For the case where the AstLinux system box cannot boot directly to a USB drive, there is a solution for that, by using the CF card to "boot" the USB flash drive, "CF + USB Combo Booting".

| Note: With runnix-0.3.3 and later, advanced users will notice that this 'secondary' (Combo Booting) disk simply requires the AstLinux "os" distribution directory and a dosfslabel of RUNNIX on a small (128MB) FAT16 (or FAT32) partition together with a CF card with a RUNNIX-bootonly image. The remainder of the unformatted 'secondary' disk will be formatted during the AstLinux setup process. This would apply for any read-write media type, even for media types where a raw byte transfer of the AstLinux flash image would not be appropriate. | Note: With runnix-0.3.3 and later, advanced users will notice that this 'secondary' (Combo Booting) disk simply requires the AstLinux "os" distribution directory and a dosfslabel of RUNNIX on a small (128MB) FAT16 (or FAT32) partition together with a CF card with a RUNNIX-bootonly image.
