Unless your BIOS supports USB drives, in which case no drivers are needed. Most newer machines do include BIOS support for USB mass-storage devices, and can even boot from them. -- Charles Dye raster(a)highfiber.com

My laptop runs winxp and does not have a floppy drive. For some reason the iso image does not boot from DVD/CD. But even if it did, freedos does not know how to use usb to get to the flash drive. winxp does not allow me to access the "hard drives" hidden areas, so the freedos sys command does not work under the dos console for winxp. So with winxp I can copy files, but not make the cf bootable. I have to start with msdos, and use the freedos sys command. However, I have apparently hit a bug in freedos where it boots but does not load config.sys or fdconfig.sys. SO I am stuck. Thanks, Steve There is no "x" in my email address.

Again, it depends on whether you are doing it once or many times. We can either send you the CF or the adapter for you to do it. Once you have the bootable CF, you can sys and/or copy another from the PC104 board. > > winxp does not allow me to access the "hard drives" hidden areas, so > the freedos sys command does not work under the dos console for winxp. Even if it does, you will sys the XP system files and crash with the rest of freedos. You have to boot from a clean freedos to "sys". > > So with winxp I can copy files, but not make the cf bootable.

You are mixing apples and oranges. > apparently hit a bug in freedos where it boots but does not load > config.sys or fdconfig.sys. SO I am stuck. I believe you. I have loaded freedos on 8M CF from 5 floppies. You can't mix any files with msdos or windows, since they have the same file names very often. That's why our highly skilled engineer have to charge you $1 per floppy (for swapping and waiting). > > Thanks, Steve > > There is no "x" in my email address. |
