To create ASM code form Pascal code to assembling and put into ROM
you can use fpkPascal
(http://www.brain.uni-freiburg.de/~klaus/pascal/fpk-pas/)
that easily permit to output Pascal program to .ASM file.
This compiler also support optimization for i386 to Pentium pro CPU
and 32 bit extender and much more function.
I forget to say that this program is FREEWARE !!!!!!!.
Yes you understand this program is freeware.

You wrong when you wrote

because the protected mode was a new features of 286 and
PM instructions isn't part of 8088 instructions set.
