Re: [OpenBIOS] Why protected mode?

That is also how you have to do if >you strive for IBM-PC BIOS compability. 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.

Other ISA port 0x80 reads (?)
by Johan Rydberg July 7, 1999

Hi people! Does any know of any commerical sold ISA cards that reads and displays information written to ISA I/O port 0x80 ? -- Johan Rydberg Net Insight AB johan.rydberg(a)netinsight.se Ingenjörsvägen 3 http://www.netinsight.se SE-117 43 STOCKHOLM phone:+46-8-685 04 16 Sweden fax: +46-8-449 22 40 mob: +46-704-53 57 21 - To Unsubscribe: send mail to majordomo(a)freiburg.linux.de with "unsubscribe openbios" in the body of the message

Newbie questions
by Brian Hurt July 6, 1999

July 6, 1999

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.

OpenBIOS POST, flash, and IO card site.
by James Oakley July 6, 1999

July 6, 1999

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. James Oakley jfunk(a)roadrunner.nf.net - To Unsubscribe: send mail to majordomo(a)freiburg.linux.de with "unsubscribe openbios" in the body of the message

port 0x80 ?
by Johan Rydberg July 5, 1999

July 5, 1999

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? -- Johan Rydberg Net Insight AB johan.rydberg(a)netinsight.se Ingenjörsvägen 3 http://www.netinsight.se SE-117 43 STOCKHOLM phone:+46-8-685 04 16 Sweden fax: +46-8-449 22 40 mob: +46-704-53 57 21 - To Unsubscribe: send mail to majordomo(a)freiburg.linux.de with "unsubscribe openbios" in the body of the message

Anyone here ?
by Thomas Petazzoni July 5, 1999

July 5, 1999

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 -- ------------------------------------------------------------------- PETAZZONI Thomas & Maxime E-mail : peta(a)club-internet.fr ICQ : 34937744 KOS-web : http://www.comports.com/kos - To Unsubscribe: send mail to majordomo(a)freiburg.linux.de with "unsubscribe openbios" in the body of the message

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 -- Johan Rydberg Net Insight AB johan.rydberg(a)netinsight.se Ingenjörsvägen 3 http://www.netinsight.se SE-117 43 STOCKHOLM phone:+46-8-685 04 16 Sweden fax: +46-8-449 22 40 mob: +46-704-53 57 21 - To Unsubscribe: send mail to majordomo(a)freiburg.linux.de with "unsubscribe openbios" in the body of the message

Writing 16bit code using the GNU assembler!

Hello people! I'm writing a BIOS for the STPC Consumer (from STMicroelectronics) using the GNU assembler.

The openBIOS
by Thomas Petazzoni July 3, 1999

July 3, 1999

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 ???

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.
