Ineed to write a few simple asm lines for pgms I am porting to Linux from DOS
where the int86(..) function was handy.

I realise that the syntax of the GNU Assembler is completely different from
MASM
or TASM, especially to access tne INTEL registers.

Thanks to the good soul which could tell me where I can find the necessary doc.
(book or otherwise).

Simple answer 1: pretend interrupts just don't work in Linux. (That's
close enough to reality anyways.)

Simple answer 2: embedding assembly in your code means you're not
porting to Linux, you're porting to an inherently nonportable
i386-based Linux. IMHO unless you're the kernel the latter is quite
inexcusable.

Have you looked in Info?
