And this continues the necessity for either a keyboard or a keyboard
simulator, does it not? My recollection is that the only way out of
protected mode (back in 286 days) was through a keyboard reset sequence.

Hi people!
Does any know of any commerical sold ISA cards that
reads and displays information written to ISA I/O port

The FAQ link from the freiburg.linux.de web page seems to be broken. I
apologize in advance for asking potientially frequently asked questions.
Is there a CVS repository for code? It looks like I'll be adding support
for the SIS530 chipset (Pentium/Socket-7), and would like to fold my code
changes back into the main codeset.
Thanks!

I've placed the schematics on my website at
http://wiley246h122.roadrunner.nf.net:2080/openbios/ (yes, it's a static
address) for the OpenBIOS development hardware. There is currently no
documentation, but the circuit is, in a way, straightforward.
If anybody can check it over and verify if it's correct I will be
forever in your debt.
For those who don't know, this is a single ISA card that allows
dual-flash functionality, standard port 0x80 POST, enhanced OpenBIOS
POST (to character LCD, actually human-readable!), and 5 general-purpose
8bit IO ports (for experimentation, education, and embedded designs).
Feel free to contact me on any issues here.

Hi people!
I have looked a bit at the sources and wondering
what port 0x80 is? I guess that it is a port
that you write information about the POST to,
but what reads it?

Hi,
I suscribed to this mailing list one week ago, but i didn't not receive
any message. Is this a technical problem ?
I read about OpenBios in a French magazine, called "Linux Mag". Your
project seems to be very interesting, that's why i suscribed to this
mailing list.
Am I really suscribed ?
Thanks to answer me through the mailing list and by private mail.
Thank you very much
Thomas, from Paris, France

How do you relocate a 16bit pointer ? Do you use the ``addr32´´
macro ?
Example:
addr32
movw $0f, %si
0:
ELF doesn't support 16-bit relocations, how do you solve this?
And I have run into another problem with the GNU assembler. If
you for example do the following:
lodsw %cs:(%si), %ax
It generates the following code:
lodsw %ds:(%si), %ax
You have to make the %cs prefix of your own in the code, by
adding a ``.byte 0x2e´´ infront of the instruction. Have you
also run into this problem

Hello people!
I'm writing a BIOS for the STPC Consumer (from STMicroelectronics)
using the GNU assembler. Does anyone else uses the GNU assembler
for writing 16bit code?

Hi,
I've downloaded some tar.gz fromm the official web site of OpenBIOS. I
found a lot of sources in it. What are those ? There are no
documentations ...
I think we should define how will be the openBIOS.... who is the
coordinator of that project ???
Thanks

I agree with your notion of a single open BIOS being better than fragmented
efforts. I think that the recent news about Phoenix selling ad space in
their BIOS adds to the need for an open source BIOS.
