Does Neutrino use BIOS int 13h to work with disk ?
What if I need to use only BIOS int13h to work with flash-disk ?
Is there any opportunity to call int 13h from my program
( I try to move my DOS program to Neutrino )
And BTW, can I boot Neutrino from FAT16 ?
Thanks.

In general know – the boot loader will generally use this if
the BIOS loader is used, but once the OS is running, it won’t
do it.

You can make an int13h call from QNX as QNX runs in protected mode.
(Both QNX4 and Neutrino.) If the flash-disk presents an IDE interface,
you may be able to just run the IDE driver, probably giving a particular
io-port and irq to it on the commandline. What sort of flash is it?

No, you can’t call int 13h from Neutrino.

Should be doable, but if working from a limitted size flash disk, you
are probably better off using a QNX filesystem on it, rather than FAT16.
Generally booting from a DOS partition is used for desktop machines to
allow an install into a Windows 95/98 partition for demo or test purposes.

Oops, yes… CAN’T is correct. Such a dangerous typo. sigh
