Of course PCs from 1990 don't support USB. >> How do you know?

Any 2004+ mainstream PC I've seen contains a BIOS version which I know supports booting from USB (since I tested these BIOS versions on some PCs). BTW, no 2004+ mainstream PC I've seen (except x86 Macs) contains EFI. Some of the BIOSes require the boot media to be formatted with MBR (as that HP bootable flash format tool creates) but some require "super-floppy" format instead (no MBR, a single partition). Or exactly: Current DOS versions require this, the BIOS just provides the storage as either Int13 disk *below* 80h (floppy) or *above*(/equal) 80h (hard disk with MBR), and since now I've seen no DOS version to provide any kind of auto-detection, or a manual override to disable/enable the partition table parsing for the boot drive no matter which Int13 unit it is. (Guess to what DOS version I'll add at least the override option ;-D ) Regards, Christian ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
