From: Steve Calfee on 13 Jun 2005 13:36 Hi, I have a PC104 system. It does not have either a floppy or a CD drive, it has a compact flash drive a: built in and an add on board for a compact flash card (like used in cameras) for drive c:. It comes with a defunct dos clone called GSDOS. Someone before me made a MSDOS bootable flash drive. Now with that I can sys: from that bios/drive a: flash and make bootable drives in the c: CF drive. And I can then do the same for other a: flash drives by using the c: drive. My problem is I would like to try freedos and drdos and others. These systems typically come with 1.4meg floppy and cd image files. I don't know how to make a bootable compact flash. The only non-dos access to the cf drives I have is via a USB/compact flash dongle for my winxp system. I can copy files onto the CF from windows, but the hidden, system areas, partition info, boot records etc also need to be inited. It is a chicken and egg thing. Once I have a bootable DOS drive I can sys copy onto other dos drives. But I do not have a bootable DOS system than can access the USB/CF dongle. I have a linux system but no compact flash reader/writer hardware. Any ideas? Thanks, Steve There is no "x" in my email address.

If so, assuming the CF is on G:, use FreeDOS sys (from a bootable FreeDOS floppy in A: for example) and just do "sys g:". If you don't have WINDOWS and only Linux, you might get something out of DOSEMU, if you set things up right. Right, MartinS

The OP has USB drive, FreeDOS knows nothing about USB at all. You must be running FreeDOS to "sys". > > If you don't have WINDOWS and only Linux, you might get something out > of DOSEMU, if you set things up right. That will map into the linux drivers (IDE or FDC), which will carefully protect the user from messing up the boot sector. > > > Right, > > MartinS

In order to use -ANY- peripheral device connected to a USB port from true DOS, you -MUST- install a third-party, DOS-based USB software driver. True DOS knows nothing about USB ports, and can't access them without a driver. There are several USB software drivers available for DOS. Try one or two, until you find one that recognizes the presence of the USB drive. Google for 'USB + DOS' (without the quotes). Once you've installed an appropriate DOS USB driver, it will then be necessary to partition, format, and sys the USB drive. Make certain that you do this with the O.S. that you'll be using on the drive. Don't try to do it with a Mikro$loth product. Frankly, I wouldn't fsck around with FreeDOS at all. DR-DOS version 7.xx is free, is much better than FreeDOS, and is a hell of a lot more stable. http://www.drdosprojects.de Have fun! |
