Hi all,

I have a Tandy 1000 TX that I would like to boot from the 5.25" floppy, which is drive B:. Isn't there a button I can hold on startup that will let me do that?

Thanks

I don't know what your exact goal is here but whenever I want to boot from a B floppy I use a DOS program called BOOT_B that shifts the system boot from drive A to drive B when the BOOT_B disk is in drive A.

Works a treat.

I've also stuck a XT-IDE BIOS in a system temporarily in order to select drive B from the boot menu.

Seems like a lot of work when simply putting a disk in drive A will automatically redirect the boot process to drive B.

Yes!

Beginning with the 1000SX, EX, and HX, Tandy used these function keys during startup:

F1 = Mono mode (disables color burst)
F2 = TV mode (same as F12 on an original 1000)
F3 = Swap floppy drive letter assignments
F4 = Slow mode (clock speed reduced to 4.77 MHz on an 8088 or 4 MHz on a 286) (or "MODE SLOW" in DOS, vs. "MODE FAST")

It ends with the TX, I believe. F3 is the OP's key to boot from Drive B.
