Bootia32.efi windows 10 download

FreeBSD can boot using UEFI on the amd64 and arm64 platforms since FreeBSD (r). More information is available in uefi(8). Like loader(8), the UEFI loader www.cronistalascolonias.com.ar supports booting from GPT UFS and ZFS filesystems and supports GELI in the loader.

Virtualised Development Environment

If you wish to test this code under a virtual environment, UEFI firmware images are available for qemu. Assuming you have a version of qemu greater than , you can download the OVMF images from here. Download the ovmf-x64 rpm file and unpack it with . You'll probably want to copy usr/share/www.cronistalascolonias.com.ar somewhere more convenient then remove the rest of the extracted files and directories. To test the code I run:

> qemu-system-x86_64 -m -serial stdio -bios www.cronistalascolonias.com.ar -hda fat:<path to boot directory>

Alternatively, to test UEFI CD support:

> qemu-system-x86_64 -m -serial stdio -bios www.cronistalascolonias.com.ar -cdrom <path to ISO image>

The boot directory contains my built www.cronistalascolonias.com.ar as well as any kernel I want to boot.

Real Hardware Gotchas

These are some issues that benno@ ran into when using real hardware (ie, not qemu) in early development:

• Filesystem not seen. FreeBSD's FAT32 code appears to sometimes create filesystems that the UEFI code can't properly read. If the filesystem is small enough, use FAT16 or FAT12 instead.

  • Please submit a PR with details if you are able to reproduce this.

Bootable UEFI memory stick or Hard Disk

To test UEFI booting on a memory stick or a hard disk, create a GPT partition table with a small EFI partition and the rest of the space dedicated to a FreeBSD UFS partition:

gpart create -s gpt da0 gpart add -t efi -s 40M da0 gpart add -t freebsd-ufs da0 newfs_msdos -F 32 -c 1 /dev/da0p1 mount -t msdosfs /dev/da0p1 /mnt mkdir -p /mnt/EFI/BOOT cp /boot/www.cronistalascolonias.com.ar /mnt/EFI/BOOT/BOOTXefi umount /mnt newfs -U -L FreeBSD /dev/da0p2

Perform the install to the UFS partition, as usual:

mount /dev/da0p2 /mnt make DESTDIR=/mnt installkernel installworld distribution echo "/dev/da0p2 / ufs rw 1 1" >> /mnt/etc/fstab umount /mnt

TODO: Use a label for the root fs instead

Create etc/fstab.

umount /mnt

CD/DVD Boot under UEFI

The approach for creating a bootable CD/DVD image for UEFI is to create a FAT filesystem image containing your loader code as it would be laid out in an EFI System Partition. This image is then attached to the CD/DVD image as a non-emulation El Torito boot image. To make an image that is bootable under both legacy BIOS and UEFI, the BIOS image is placed first and the UEFI image is placed as an alternate. More information can be found here.

A sample boot ISO can be created using the following steps.

Create a FAT filesystem image and place our loader in it in the default path that UEFI will look for:

> dd if=/dev/zero of=www.cronistalascolonias.com.ar bs=4k count= > mdconfig -a -t vnode -f www.cronistalascolonias.com.ar > newfs_msdos -F 32 -c 1 -m 0xf8 /dev/md0 > mount -t msdosfs /dev/md0 /mnt > mkdir -p /mnt/EFI/BOOT > cp www.cronistalascolonias.com.ar /mnt/EFI/BOOT/BOOTXefi > umount /mnt > mdconfig -d -u 0

We now have our UEFI boot image. The next step is to make the ISO image. We assume that you have a directory called image containing the file structure you want in your ISO.

> makefs -t cd -o bootimage='i;www.cronistalascolonias.com.ar' -o no-emul-boot -o rockridge -o label="UEFItest" -o publisher="test" www.cronistalascolonias.com.ar image

You should now have an ISO image in www.cronistalascolonias.com.ar that will boot using UEFI.

The version that is built for FreeBSD 11 snapshots by the release scripts has multiple boot images attached in order to support BIOS and UEFI. You can do something similar by the following:

> makefs -t cd -o 'bootimage=i;www.cronistalascolonias.com.ar' -o no-emul-boot -o 'bootimage=i;/boot/cdboot' -o no-emul-boot -o rockridge -o label="UEFItest" -o publisher="test" www.cronistalascolonias.com.ar image

Bootable Image from NanoBSD

> cd $TOP/tools/tools/nanobsd/embedded > sh ../www.cronistalascolonias.com.ar -c www.cronistalascolonias.com.ar

The bootable image will be in $TOP/../qemu-amduefi/obj/_www.cronistalascolonias.com.ar2 that you can feed to qemu, as described in the Virtualized Development Environment section above. You can also put it on a USB stick.
