[PATCH] advanced_bootmenu: up to 35 entries (2 pages if >18), numpad support (console)
by Mike Banon April 25, 2020

April 25, 2020

Add support for up to 35 boot menu entries (2 pages if >18). To solve the ">10" problem currently experienced by SeaBIOS users (there are no 11, 12, etc. keys on a keyboard - so impossible to choose the last menu entries if you got >10 entries because of multiple hard drives / secondary payloads / floppies) - the boot menu has been extended to the letter keys. NOTE: TPM menu has been moved from T to M letter: it is at the end of keyboard's 3rd row of letters and "Trusted" is adjective while "Module" is a noun; alternatively could press '-'. Also, add support for a numpad. Small USB numpad could be really convenient for choosing the boot entries at coreboot boards used as (maybe headless) servers. '/' char on numpad could be used to open the boot menu or to exit it. If there are >10 boot menu entries - the numpad console interface will be enabled: press one or two digit keys and then ENTER to confirm your choice, or remove a digit by pressing the '.Del' key. Also you could call TPM with '-' key at any moment, or boot with a single key press of your fullsize keyboard. Signed-off-by: Mike Banon <mikebdp2 at gmail.com> (patch body is after the testing instructions below) This "advanced_bootmenu" patch is much more useful when used together with my "multiple_floppies" patch: [SeaBIOS] [PATCH v2] ramdisk: search for all available floppy images instead of one https://mail.coreboot.org/pipermail/seabios/2018-December/012670.html Sadly I haven't done the suggestions by Kevin (I have so many unfinished tasks) so the "multiple_floppies" patch is also not merged yet. But you could install both patches to your coreboot by executing this script while at ./coreboot dir: https://pastebin.com/raw/hv9sSuMU And here is a coreboot image for QEMU with these two patches applied and my collection of wonderful and useful floppies added to popular the entries list: https://github.com/mikebdp2/floparchive/blob/master/coreboot.rom?raw=true Descriptions of the most prominent floppies could be found here: http://dangerousprototypes.com/docs/Lenovo_G505S_hacking#Useful_floppies Run this coreboot.rom by executing this QEMU command: (some floppies are 64-bit) qemu-system-x86_64 -L . -m 768 -localtime -vga vmware -net nic,model=rtl8139 \ -net user -soundhw ac97 -bios ./coreboot.rom -boot menu=on -serial stdio Best regards, Mike Banon diff --git a/src/boot.c b/src/boot.c index 9f82f3c..f94dd27 100644 --- a/src/boot.c +++ b/src/boot.c @@ -463,6 +463,7 @@ get_keystroke(int msec) * Boot menu and BCV execution ****************************************************************/ +#define BOOTMENU_PAGE_SIZE 18 #define DEFAULT_BOOTMENU_WAIT 2500 // Show IPL option menu. @@ -478,59 +479,282 @@ interactive_bootmenu(void) ; char *bootmsg = romfile_loadfile("etc/boot-menu-message", NULL); - int menukey = romfile_loadint("etc/boot-menu-key", 1); - printf("%s", bootmsg ?: "\nPress ESC for boot menu.\n\n"); + int menukey = romfile_loadint("etc/boot-menu-key", 1); // custom menukey + printf("%s", bootmsg ?: "\nPress ESC or \\ / slash for boot menu.\n\n"); free(bootmsg); u32 menutime = romfile_loadint("etc/boot-menu-wait", DEFAULT_BOOTMENU_WAIT); enable_bootsplash(); int scan_code = get_keystroke(menutime); disable_bootsplash(); - if (scan_code != menukey) + if (scan_code != menukey && // custom menukey + scan_code != 1 && // ESC + scan_code != 43 && // '\' char on keyboard + scan_code != 53 && // '/' char on keyboard + scan_code != 98) { // '/' char on numpad + if (scan_code == -1) + printf("No key pressed.\n"); + else + printf("Not a menukey pressed.\n"); return; + } while (get_keystroke(0) >= 0) ; - printf("Select boot device:\n\n"); wait_threads(); - // Show menu items + char keyboard_keys[35] = {'1','2','3','4','5','6','7','8','9','0', + 'q','w','e','r','t','y','u','i','o','p', + 'a','s','d','f','g','h','j','k','l', + 'z','x','c','v','b','n'}; /* m = TPM */ + int numpad_scancodes[10] = { 82, 79, 80, 81, 75, 76, 77, 71, 72, 73 }; + int numpi = 0; // Key index: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. + int digits = 0; // Numerical length of a current choice number. + int decode = 0; // Decode the current choice number into a letter? + int entry_id = 0; + char desc[77]; + + printf("Select boot device"); + + // Show menu items after counting them and determining a number of pages. + // Only 35 boot menu items (36 if to count a TPM) are supported currently. + int maxmenu = 0; struct bootentry_s *pos; - hlist_for_each_entry(pos, &BootList, node) { - char desc[77]; + hlist_for_each_entry(pos, &BootList, node) maxmenu++; - printf("%d. %s\n", maxmenu + + if (maxmenu > 10) { + if (maxmenu > 35) + maxmenu = 35; + if (maxmenu > BOOTMENU_PAGE_SIZE) + printf(" - page 1 :"); + else + printf(": "); + printf(" // press ENTER after your numpad input"); + if (maxmenu > BOOTMENU_PAGE_SIZE) + printf(" - if any -\n " + " // - or to switch between the pages...\n"); + else + printf(" (if any)\n\n"); + } else { + printf(":\n\n"); + } + + hlist_for_each_entry(pos, &BootList, node) { + if (entry_id == BOOTMENU_PAGE_SIZE) // Show only the first page. + break; + printf("%c. %s\n", keyboard_keys[entry_id] , strtcpy(desc, pos->description, ARRAY_SIZE(desc))); + entry_id++; } + int tpm_cshm = 0; if (tpm_can_show_menu()) { - printf("\nt.

Custom-sized, large floppy images?
by Rafael Send April 4, 2020

April 4, 2020

Hi, I'm working on stuffing a bootable Linux distro into coreboot. In QEMU I already succeded by using coreboot's built-in kernel loading mechanism, but that's without SeaBIOS. I'd love to have it as a SeaBIOS payload so I can also boot other things, but I guess I'd have to create a custom-sized floppy image for this or figure out how to create an ELF payload out of a Linux kernel (I'm open to either, but I wasn't able to find any documentation on the ELF method). The guy who put Win 3.1 in coreboot attempted the floppy method, but according to his article he did not find success with this method due to unknown and complex issues in the floppy-side logic of SeaBIOS. So, I'm making the question explicit: What would it take to support custom-sized floppy images? In particular, I'm thinking of a 16MB device... Alternatively, would it be possible to create an ELF file out of a Linux kernel+initrd / bootable image? Cheers, Rafael

Booting Memtest86+ from CBFS fails
by Martin Kepplinger Nov. 8, 2019

Nov. 8, 2019

Hi, I use the simple coreboot config https://github.com/merge/skulls/blob/master/x230/free-defconfig-555419f356 on today's coreboot master branch HEAD (403f433238), using SeaBIOS 1.12.1. When choosing memtest86+ in SeaBIOS' menu, "Booting from CBFS" gets printed but nothing else happens. Booting into nvramcui or coreinfo works though. (earlier, at least on coreboot 555419f356, using the same version of SeaBIOS, things were fine). Can you imagine why? thanks, martin

[PATCH v3 0/2] Add additional resolutions for 16:9 displays: 1600x900 and 2560x1440
by Uwe Kleine-König Oct. 17, 2019

Oct. 17, 2019

Hello, this is my attempt to address the review comments I got for v2: - Gerd pointed out that cbvesa should only use the modes where memmodel == MM_DIRECT. - Kevin noted that reading global variables need the GET_GLOBAL wrapper. (I would have expected that the compiler does the right thing here. Probably I'm still to wet behind the ears here :-) Note this is only compile tested.

[QEMU] [PATCH v5 0/8] Add Qemu to SeaBIOS LCHS interface
by Sam Eiderman Aug. 25, 2019

Aug. 25, 2019

v1: Non-standard logical geometries break under QEMU. A virtual disk which contains an operating system which depends on logical geometries (consistent values being reported from BIOS INT13 AH=08) will most likely break under QEMU/SeaBIOS if it has non-standard logical geometries - for example 56 SPT (sectors per track). No matter what QEMU will guess - SeaBIOS, for large enough disks - will use LBA translation, which will report 63 SPT instead. In addition we can not enforce SeaBIOS to rely on phyiscal geometries at all. A virtio-blk-pci virtual disk with 255 phyiscal heads can not report more than 16 physical heads when moved to an IDE controller, the ATA spec allows a maximum of 16 heads - this is an artifact of virtualization. By supplying the logical geometies directly we are able to support such "exotic" disks. We will use fw_cfg to do just that. v2: Fix missing parenthesis check in "hd-geo-test: Add tests for lchs override" v3: * Rename fw_cfg key to "bios-geometry". * Remove "extendible" interface. * Add cpu_to_le32 fix as Laszlo suggested or big endian hosts * Fix last qtest commit - automatic docker tester for some reason does not have qemu-img set v4: * Change fw_cfg interface from mixed textual/binary to textual only v5: * Fix line > 80 chars in tests/hd-geo-test.c Sam Eiderman (8): block: Refactor macros - fix tabbing block: Support providing LCHS from user bootdevice: Add interface to gather LCHS scsi: Propagate unrealize() callback to scsi-hd bootdevice: Gather LCHS from all relevant devices bootdevice: Refactor get_boot_devices_list bootdevice: FW_CFG interface for LCHS values hd-geo-test: Add tests for lchs override bootdevice.c | 148 +++++++++--- hw/block/virtio-blk.c | 6 + hw/ide/qdev.c | 7 +- hw/nvram/fw_cfg.c | 14 +- hw/scsi/scsi-bus.c | 15 ++ hw/scsi/scsi-disk.c | 14 ++ include/hw/block/block.h | 22 +- include/hw/scsi/scsi.h | 1 + include/sysemu/sysemu.h | 4 + tests/Makefile.include | 2 +- tests/hd-geo-test.c | 582 +++++++++++++++++++++++++++++++++++++++++++++++ 11 files changed, 774 insertions(+), 41 deletions(-) -- 2.13.3

Int 10h and custom character set
by Konstantin Novikov July 12, 2019

July 12, 2019

Hello, dear SeaBIOS community. I need your help. I want to change character set with my own character table. Now I'm trying to use Int 10h, function 11h. As SeaBIOS works with mode #3 by default (text mode, 80x25 cells), I'm calling subservice 0h for set my table with 8x16 characters. But It' doesn't work. Characters are changed, but symbol's form isn't depends on what's my table contains. I think, It happens because I need to set table pointer in registers es and bp. In flat model I can't get value of segment, which contains my table. I tried to write 0 in es register and allocate memory in low zone - didn't changed anything. So, can you help me? Maybe, I just using wrong way, and solution is much easier? Thank you for attention. Novikov Konstantin

Keyboard is not working on MacBook Air 5,2 and MacBook Pro 10,1
by Evgeny Zinoviev July 6, 2019

July 6, 2019

Hi folks. I've recently ported coreboot on MBA 5,2 (13'' mid 2012 model) and MBP 10,1 (15'' mid 2012 retina model). The integrated keyboard on these models is connected as a USB device, not PS/2. I have tested GRUB, SeaBIOS and Tianocore payloads, and the keyboard works in GRUB and Tianocore but not in SeaBIOS. I was advised to send a log to this mailing list. It was created with SEABIOS_DEBUG_LEVEL=9. I'm not yet familiar with SeaBIOS code, but with your help perhaps I can debug and fix this.

We will use fw_cfg to do just that. v2: Rename bootdevices fw_cfg key to bios-geoemtry v3: Change fw_cfg interface from mixed binary/textual to textual only Squash commit "config: Add toggle for bootdevice information" v4: * Rename TRANSLATION_MACHINE to TRANSLATION_HOST * Rename "overriden" translation name to "host-supplied" * Rename overriden_lchs_supplied() to host_lchs_supplied() * Move sectors and heads check to host_lchs_supplied() * Reuse duplicate code in boot.c Sam Eiderman (5): geometry: Read LCHS from fw_cfg boot: Reorder functions in boot.c boot: Build ata and scsi paths in function geometry: Add boot_lchs_find_*() utility functions geometry: Apply LCHS values for boot devices src/Kconfig | 7 ++ src/block.c | 18 +++- src/block.h | 1 + src/boot.c | 273 +++++++++++++++++++++++++++++++++++++++++---------- src/hw/ahci.c | 1 + src/hw/ata.c | 8 ++ src/hw/esp-scsi.c | 2 + src/hw/lsi-scsi.c | 2 + src/hw/megasas.c | 1 + src/hw/mpt-scsi.c | 2 + src/hw/pvscsi.c | 1 + src/hw/virtio-blk.c | 2 + src/hw/virtio-scsi.c | 2 + src/util.h | 6 ++ 14 files changed, 272 insertions(+), 54 deletions(-) -- 2.13.3
