Re: Function BB of Int 1Ah

Not I.
I don't see BBh for Int 0x1A in RBIL (Ralf Brown's Interrupt List) either.
Are you sure the BBh is correct? There is one listed with 0Bh and another
that has 8Bh... A few of the AX = Bxxxh functions are related to PCI and
Plug-n-Play - which have specifications.

Help.Missing interrupt from rtl8139 network card.

2009-11-25T02:11:09Z

Hi.
I am writting a small os base on x86 arch.
I have just written a rtl8139 driver for my os.the device's interrupt
vector is 11.
When I run my os, I can 'ping' it through windows for a while.
But after a few minutes, the rtl8139 network card has not produce any

I can assure the os is not dead.Because it can receive the interrupt

An OS generator?

2009-11-24T23:57:45Z

It seems someone wrote an OS generator. It generates a RTOS from
information for a FSM.
"Given a set of 'tasks' written in C, WhatOS generates a finite-state
machine operating system in C, that is architecture independent and small
enough to run even on resource-limited 8-bit microcontrollers."

Attributes of a memory request or address space request

2009-11-22T19:24:12Z

Below is an attempt to come up with a maximal set of attributes that
might be needed in a memory request. (Really it's an address space
request as the actual memory can be allocated by a page fault routine
as needed.)
In the general case are all of these needed? Are any other attributes
needed or advisable so that an address space allocator can be most

Re: Embedding assembler in a language

2009-11-20T22:50:22Z

Either way.
Sure, why not? It may be slow, but it could be useful for bootstrapping an
x86 OS independent of cpu mode. To fully implement useable subset of x86
instructions, one needs:
1) math operations on one of: register, stack, or memory
2) ability to move data between register and stack
3) (optionally) ability to move data between registers
