Solution:

The following is for your reference: (1) CHOICE.COM => When you reboot 5510, you can see there are three items to let you select what you want to do about your next step. If you don't want this function, you can modify autoexec.bat and remove this program. (2) VDISK.SYS => You can use this driver to create a virtual disk from SRAM. The usage is shown as below: DEVICE=VDISK.SYS 64 128 16 (3) TRANSFER.EXE => When you transfer a file from your host PC to 5510, you need this program to handle it, such as [File transfer] ( Alt-T ), [Program] function under 5510 Utility. (4) DLFFS.EXE => This driver is for datalight file system, you must run this driver to transfer flash to disk, after that, you can use DOS command such as "del", "dir", and so on. Please refer to config.sys to learn how to use it. (5) DLFMT.EXE => If you want to format flash disk ( that means your Drive D of 5510/P31 ), you must use this program. (6) ROMDISK.EXE => Before you download files of ALLFILE directory, you need to transfer these files to HEX file, then download this HEX file to 5510 flash ROM, 5510 would call this program to do that automatically when you execute "Program" function under ADAM5510.EXE.
