[PATCH 5/4] Add geodevga_set_mode() function
by Christian Gmeiner 01 Sep '12

01 Sep '12

We need to set the DC register visibility before we can call stdvga_set_mode().

[PATCH 1/4] change return value of dc_setup() and vp_setup() to void
by Christian Gmeiner 01 Sep '12

There is no reason to have a return value of type int for dc_setup() and vp_setup() as they return nothing else then 0. Also add missing static to vp_setup().

[ANNOUNCE] SeaBIOS 1.7.1
by Kevin O'Connor 31 Aug '12

31 Aug '12

The 1.7.1 version of SeaBIOS has now been released. For more information on the release, please see: http://seabios.org/Releases New in this release: * Initial support for booting from USB attached scsi (USB UAS) drives * USB EHCI 64bit controller support * USB MSC multi-LUN device support * Support for booting from LSI SCSI controllers on emulators * Support for booting from AMD PCscsi controllers on emulators * New PCI allocation code on emulators. Support 64bit PCI bars and mapping them above 4G. * Support for non-linear APIC ids on emulators. * Stack switching for 16bit real mode irq handlers to reduce stack footprint. * Support for custom storage in the memory at 0xc0000-0xf0000. No longer reserve memory for custom storage in first 640k. * Improved code generation for 16bit segment register loads * Boot code will now (by default) reboot after 60 seconds if no boot device found * CBFS and FWCFG "files" are now only scanned one time * Several bug fixes For information on obtaining SeaBIOS, please see: http://seabios.org/Download

Re: [SeaBIOS] DC Mapping
by Fred . 31 Aug '12

31 Aug '12

Can SeaBIOS output colored text? It would be good to highlight keys. such as "Press F12 for menu" then highlight "F12". Other BIOS such as Award and AMI can use colors in text. Example "Press F12 for boot menu", then "F12" is in highlighted color.

iasl-option not working
by Kevin O'Connor 31 Aug '12

31 Aug '12

Hi Michael, I was running through the SeaBIOS release checks when I found that the new iasl-option code in the Makefile seems to choke on older versions of iasl (for example, version 20120123 as shipped with fc13). Can you verify if the iasl detection still works properly for you with the patch below? -Kevin >From 51755c3b5ed9dcdfdef8cee56631d68642bde416 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor <kevin(a)koconnor.net> Date: Wed, 29 Aug 2012 21:27:37 -0400 Subject: [PATCH] Make iasl option check work with older versions of iasl.

DC Mapping
by Christian Gmeiner 31 Aug '12

31 Aug '12

Hi all, I posted some patches to the ML and want to discuss a part of if - DC mapping. After looking at the patches again, I think I miss understood something :) DC mapping is used to be able to configure the display controller via the defined memory region. A0000 Graphics Mode B0000 Monochrome Text Mode B8000 Color Text Mode That would mean that if I map the DC to A0000 I can access its registers via A0000 + register offset or? If this is the case then drop my last two patches. The "bad" thing is that I don't have a "normal" lx800 platform to test all my patches. --- Christian Gmeiner, MSc

What do I pass to cbfs_run_payload() after finding the payload with romfile_find() ?
by Dave Frodin 30 Aug '12

30 Aug '12

I'm having a problem finding/loading/executing a payload from seabios which is now using the romfile functions for cbfs (commit 59d6ca52a7eba5). I do have the cpu_to_be32() patch to get the correct payload destination address. Here's what I had previously that worked before the change... // Output the LCD splash image to the Explorer board struct cbfs_file *file; dprintf(1,"Looking for Explorer LCD splash payload ... "); file = cbfs_finddatafile("img/explorer-splash"); if(file) { dprintf(1," found file [%s]. Loading it...\n ",file->filename); cbfs_run_payload(file); } else dprintf(1,"could NOT find it!\n"); This is where I'm at after the change ... // Output the LCD splash image to the Explorer board struct romfile_s *file; dprintf(1,"Looking for Explorer LCD splash payload ... "); file = romfile_find("img/explorer-splash"); if(file) { dprintf(1," found file [%s]. Loading it...\n ",file->name); <=== everything works up to here // cbfs_run_payload(); } else dprintf(1,"could NOT find it!\n"); The cbfs_run_payload is expecting (cbfs_file *). How do I extract what cbfs_run_payload() wants from what I got back from romfile_find() ? Thanks in advance, Dave
