Some of the recent changes to smbios that look like possible culprits are: Make SMBIOS table pass MS SVVP test Use MaxCountCPUs during building of per cpu tables. Add malloc_high/fseg() and rework bios table creation to use them. There were other changes, but the comments indicate they were only ports of changes already in bochs. I suppose it's also possible the lack of smbios is turning off some other feature in the guest (eg, acpi) that's the real culprit. -Kevin

[PATCH] support piix PAM registers in KVM
by Gleb Natapov 19 Jun '11

19 Jun '11

Without this BIOS fails to remap 0xf0000 memory from ROM to RAM so writes to F-segment modify ROM content instead of memory copy. Since QEMU does not reloads ROMs during reset on next boot modified copy of BIOS is used.

[PATCH V4 0/8] Add TPM support to SeaBIOS
by Stefan Berger 19 May '11

19 May '11

The following set of patches add TPM and Trusted Computing support to SeaBIOS. In particular the patches add: - a TPM driver for the Qemu's TPM TIS emulation (not yet in Qemu git) - ACPI support for the TPM device (SSDT table) - ACPI support for measurement logging (TCPA table) - Support for initialzation of the TPM - Support for the TCG BIOS extensions (1ah handler [ah = 0xbb]) (used by trusted grub; http://trousers.sourceforge.net/grub.html) - Static Root of Trusted for Measurement (SRTM) support - Support for S3 resume (sends command to TPM upon resume) - TPM-specific menu for controlling aspects of the TPM - [An optional test suite for the TIS interface] All implementations necessarily follow specifications. When all patches are applied the following services are available - SSDT ACPI table for TPM support - initialization of the TPM upon VM start and S3 resume - Static root of trust for measurements (SRTM) that measures (some) data of SeaBIOS in TCPA ACPI table - 1ah interrupt handler offering APIs for measuring and sending commands to the TPM (trusted grub uses them) - User menu for controlling aspects of the state of the TPM v4: - if ! has_working_tpm() now returns error code everywhere - tis_test.c now also under LGPLv3 - in inthandler, pulled set_cf() out of switch and then only call it in the default case where we need to indicate that a function is not implemented v3: - some nits here and there - calling timer_setup now after S3 resume v2: - following Kevin's comment - refactoring code so that every patch compiles Regards, Stefan

[PATCH] skip interactive boot menu if only one boot device present

my bios.bin.elf is too big
by Rock Cui 07 Apr '11

07 Apr '11

hello, everyone, I'm a seabios newer. I want to build a coreboot image with seabios as its payload. I need the seabios(bios.bin.elf) to be smaller then 1M, but I got a 1.3M one after building . I did not change anything in my seabios host directory. I don't know how to decrease the size. My colleague had built a smaller image(64k) with cygwin in win7, but he also does not know how to help me. So if anyone could give me some advices, that will be highly appreciated!^_^ PS: I don't know whether this subject line meets the requirements, if not, please tell me, thinks a lot!

GSoC: Xen.org project to implement PV driver frontend for SeaBIOS
by Ian Campbell 06 Apr '11

06 Apr '11

Hi, (I was unsure what the appropriate mailing list for this was, apologies for the cross post) You may or may not be aware that Xen intends to switch to using SeaBIOS as part of switching to using upstream qemu as our device model (hopefully in our next major release later this year). The switch to SeaBIOS is currently a WIP by Anthony Perard (who did the Xen port to upstream qemu). This is mainly a heads up that we have several students interested in a project which I am mentoring to add Xen PV frontends (particularly disk) to SeaBIOS . You can see a brief description of the project near the end of the table at http://wiki.xen.org/xenwiki/GSoC_2011_ideas. Obviously one of the main goals will be to work with the SeaBIOS (and if necessary qemu) communities as well as Xen.org in order to produce patches which can can be submitted to the relevant upstreams. If/when we have an actual student assigned to the project I will ask them introduce themselves too. If anyone want to be more involved with this work (e.g. as a backup mentor or whatever) then please do let me know. Cheers, Ian.
