I have corrupted firmware of my modem. I have read that it's possible to re-flash the firmware and I found a clone of my modem Billion Bipac 711CE. Here is a link to download this re-flashing utility http://au.billion.com/downloads/711CE_reflash_utility.zip
. What do I need now is putting my PC in DOS. I tried to use both Windows 98SE and Windows XP floppy boot disks created under those mentioned above operating systems but I couldn't reach the C:\FLASH to which I have copied the content of folder DOS Flash Utility. I really faced the problem where to find clear DOS with USB drivers and perhaps LAN support too, because although modem has to be flashed via USB, the manufacturer advises to plug the network cable as well. Please help me to find that DOS as well as instructions on how to install it on CD or HDD.
