How to change Seabios configuration to disable Legacy Bios and enable UEFI bios
by Fatemi (US), Afsheen K 24 Mar '21

24 Mar '21

Dear SeaBios Support, I'm using KVM on a Redhat 7.3. I'm having difficulty creating a Windows 10 VM as it complains in the beginning of the installation that the BIOS is set to Legacy which should be disabled and set to UEFI. The BIOS of the physical host is indeed set to UEFI but the BIOS of the virtual box that KVM is using(Seabios version 1.9.1-5.el7) appears to be set to Legacy. I don't know how to reconfigure Seabios to change it to UEFI. The VM boot menu doesn't have any options to go to its bios. Apparently there should be some "kemu" or similar command with correct parameters which might do the trick. Any help would be appreciated very much. Regards, Afsheen

[PATCH 1/1] usb-hid: Increase MAX_KBD_EVENT
by Stefan Ott 11 Mar '21

11 Mar '21

Some USB keyboards use max packet sizes beyond the current maximum supported by SeaBIOS. This increases the available size to support keyboards such as the Matias Ergo Pro.

[PATCH 00/31] Add support for PA-RISC CPU target
by Helge Deller 09 Mar '21

09 Mar '21

This patchset modifies SeaBIOS source code to be able to build a firmware for the PA-RISC CPU architecture. This firmware can then be used to boot a virtual PA-RISC machine with PA-Linux and HP/UX on QEMU. Where possible existing SeaBIOS drivers and infrastructure is reused. Since PA-RISC is native 32/64-Bit, the various segment accessors are not needed and replaced by simple variable accesses. Helge Deller (31): Add config option for PA-RISC arch biosvar.h: Add accessors for various BIOS data areas Drivers: Use get_bda_ptr() BDA accessor byteorder.h: Add endianess conversion functions farptr.h: Add FLATPTR* accessor functions for parisc font.c: Disable built-in x86 font on parisc paravirt.h: Add PORT_QEMU_CFG_CTL for parisc pciinit.c: Initialize PA-RISC Dino PCI chip shadow.c: Compile int3 inline assembly on x86 only Add portaddr_t typedef to specify I/O port addresses ata.c: Allow to boot on PA-RISC ata.h: Add ATA IDE port addresses for PA-RISC blockcmd.c: Prevent unaligned access crash on PA-RISC scsi: Add fields for specifying target and lun of SCSI devices lsi-scsi.c: Convert SCSI script to little endian pci.c: Add PCI ports for PA-RISC and access PCI bus in little-endian rtc.h: Add CMOS/RTC addresses for PA-RISC serialio.h: Add serial port adresses for PA-RISC malloc.c: Implement a PA-RISC specific malloc() output.c: Add PA-RISC specific output behaviour output.c: Make printf() capable to print 64bit int values romfile.c: return values are returned as little-endian sercon.c: Use SEROFF_IIR constant stacks.h: Provide replacement for thread functions when !CONFIG_THREADS version.c: Mark version strings const x86.h: Provide replacement functions for PA-RISC parisc: Add PA-RISC related code string.c: reimplement mem*_far() functions for PA-RISC boot.c: Add boot disc chooser for PA-RISC block.c: Allow PA-RISC to boot from ATA drives ata.c: Add missing endianess conversion functions Makefile | 9 +- Makefile.parisc | 192 ++++ src/Kconfig | 54 +- src/biosvar.h | 31 + src/block.c | 10 +- src/block.h | 2 + src/boot.c | 48 + src/byteorder.h | 74 ++ src/farptr.h | 14 +- src/font.c | 2 + src/fw/csm.c | 2 +- src/fw/paravirt.h | 7 + src/fw/pciinit.c | 53 +- src/fw/shadow.c | 2 + src/hw/ata.c | 70 +- src/hw/ata.h | 14 +- src/hw/blockcmd.c | 17 +- src/hw/blockcmd.h | 2 +- src/hw/esp-scsi.c | 2 +- src/hw/lsi-scsi.c | 6 +- src/hw/megasas.c | 2 +- src/hw/mpt-scsi.c | 2 +- src/hw/pci.c | 13 +- src/hw/pvscsi.c | 2 +- src/hw/rtc.h | 7 + src/hw/serialio.c | 2 +- src/hw/serialio.h | 10 +- src/hw/usb-msc.c | 2 +- src/hw/usb-uas.c | 2 +- src/hw/virtio-scsi.c | 2 +- src/malloc.c | 4 +- src/malloc.h | 8 +- src/output.c | 56 +- src/parisc/b160l.h | 630 +++++++++++ src/parisc/head.S | 319 ++++++ src/parisc/hppa.h | 370 +++++++ src/parisc/hppa_hardware.h | 49 + src/parisc/lasips2.c | 66 ++ src/parisc/lasips2.h | 17 + src/parisc/malloc.c | 91 ++ src/parisc/pafirmware.lds.S | 69 ++ src/parisc/parisc.c | 1997 +++++++++++++++++++++++++++++++++++ src/parisc/pdc.h | 694 ++++++++++++ src/parisc/sti.c | 179 ++++ src/parisc/sticore.h | 326 ++++++ src/parisc/stirom.c | 652 ++++++++++++ src/parisc/timer.c | 103 ++ src/post.c | 2 +- src/romfile.c | 4 +- src/sercon.c | 2 +- src/serial.c | 4 +- src/stacks.h | 17 +- src/string.c | 27 +- src/types.h | 8 +- src/version.c | 4 +- src/x86.h | 6 + 56 files changed, 6236 insertions(+), 123 deletions(-) create mode 100644 Makefile.parisc create mode 100644 src/parisc/b160l.h create mode 100644 src/parisc/head.S create mode 100644 src/parisc/hppa.h create mode 100644 src/parisc/hppa_hardware.h create mode 100644 src/parisc/lasips2.c create mode 100644 src/parisc/lasips2.h create mode 100644 src/parisc/malloc.c create mode 100644 src/parisc/pafirmware.lds.S create mode 100644 src/parisc/parisc.c create mode 100644 src/parisc/pdc.h create mode 100644 src/parisc/sti.c create mode 100644 src/parisc/sticore.h create mode 100644 src/parisc/stirom.c create mode 100644 src/parisc/timer.c -- 2.29.2

It seems that the windows install iso cause this behavior and the seabios source code prove this. --- roms/seabios/src/boot.c static void boot_cdrom(struct drive_s *drive) {     if (! CONFIG_CDROM_BOOT)         return;     printf("Booting from DVD/CD...\n");     int status = cdrom_boot(drive);     if (status) {         printf("Boot failed: Could not read from CDROM (code %04x)\n", status);         return;     }     u8 bootdrv = CDEmu.emulated_drive;     u16 bootseg = CDEmu.load_segment;     tpm_add_cdrom(bootdrv, MAKE_FLATPTR(bootseg, 0), 512);     /* Canonicalize bootseg:bootip */     u16 bootip = (bootseg & 0x0fff) << 4;     bootseg &= 0xf000;     call_boot_entry(SEGOFF(bootseg, bootip), bootdrv); } --- Best regards, YiguangChen

Hello, Yiguang! If I'm not mistaken, 1st "Booting from DVD/CD..." is generated by SeaBIOS: https://github.com/coreboot/seabios/blob/58a44be024f69d2e4d2b58553529230abd… But 2nd "Press any key to boot from CD or DVD..." is shown by loader from CD. If other CDs boot without waiting for keypress, it's not SeaBIOS. That is, you'll need to tune the loader on CD itself to remove the message. Best regards, Valentine.

How to boot from DVD/CD automatically, instead of pressing a key by hand?
by Yiguang Chen 01 Mar '21

01 Mar '21

Most time, When a vm with seabios start. The bios will display such info: ----- Seabios (version rel-1.13-0 ......) Machine UUID ... IPXE .. IPXE.. Booting from DVD/CD... Press any key to boot from CD or DVD. --- It means that have a bootable cdrom to boot. But If we want to boot from cdrom, we must press any key as what the warning had said. If it is possible to boot from DVD/CD automatically, instead of pressing a key by hand? Looking forward to your feedback, YiguangChen
