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.

Also, I would like to know how to get the necessary program to make a bootable CF via a sandisk USB/CF interface running on winxp. There is no "x" in my email address.

You don't want to sys through USB, since the boot device would be incorrect. We use IDE-CF adapter to sys from floppy. That way, the boot device would be same as running from your PC104 (hopefully, primary master). You might have to try secondary master. However, if your board can boot from either CF, perhaps it does not matter. Dos is not as picky about primary vs. secondary. If you only need to do it once, then we can just send you the CF. If you need to do it more than once, then you should get the adapter as well. See: http://cfd.info-for.us > > > 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 |
