通过 dd 命令写入 helloworld_x86_64-qemu-q35.bin

$ make A=apps/helloworld ARCH=x86_64 GRAPHIC=on SMP=1
$ qemu-system-x86_64 -m 128M -smp 1 -machine q35 -kernel apps/helloworld/helloworld_x86_64-qemu-q35.elf --nographic

对比之前烧写 redox 的 u 盘 diskutil list 的返回信息

$ sudo dd if=./livedisk.iso of=/dev/disk3 bs=1m
 256MiB 0:08:51 [ 493KiB/s] [================================================================================================================>] 100%

   0:      GUID_partition_scheme                        *8.1 GB     disk3

   2:                        EFI NO NAME                 1.0 MB     disk3s2
   3:           Linux Filesystem                         265.3 MB   disk3s3

应该是分区信息没有写入 u 盘，所以还需要解决把 helloworld_x86_64-qemu-q35.bin 生成一个 livedisk.iso 的办法。

试了一下，把 helloworld_x86_64-qemu-q35.bin 写入 redox 的 /dev/disk3s3 和 /dev/disk3s1 这2个分区，启动也看不到输出信息。

覆盖 /dev/disk3s3 Linux Filesystem 分区

$ sudo dd if=apps/helloworld/helloworld_x86_64-qemu-q35.bin of=/dev/disk3s3 bs=1m
Password:
0+1 records in
0+1 records out
61760 bytes transferred in 0.038055 secs (1622917 bytes/sec)
$ diskutil eject /dev/disk3
Disk /dev/disk3 ejected

u盘启动结果：vga上显示报错：无法找到 redoxFS 。
怀疑应该是 helloworld 覆盖了之前 Linux Filesystem 的地方，也就是 redoxFS 所在位置。

覆盖 /dev/disk3s1 Bios Boot Partition 分区

$ sudo dd if=apps/helloworld/helloworld_x86_64-qemu-q35.bin of=/dev/disk3s1 bs=1m
0+1 records in
0+1 records out
61760 bytes transferred in 0.047430 secs (1302135 bytes/sec)

u盘启动结果：vga上显示 Stage 1 的内存信息后，卡在 Stage 2 就没有输出了

覆盖 /dev/disk3s2 EFI NO NAME 分区

$ sudo dd if=apps/helloworld/helloworld_x86_64-qemu-q35.bin of=/dev/disk3s2 bs=1m
Password:
0+1 records in
0+1 records out
61760 bytes transferred in 0.037279 secs (1656702 bytes/sec)

u盘启动结果：仍然能够正常启动 redox，这个分区应该不影响 redox 正常启动

通过 gdisk 命令查看 livedisk.iso 的分区结构，得到如下信息：

$ gdisk livedisk.iso

可以得到 BIOS 分区，其实是在 iso 文件偏移 First sector: 34 (at 17.0 KiB) 也就是 17K = 17408 字节处

尝试直接把 helloworld_x86_64-qemu-q35.bin 写入偏移地址 17408 ，启动仍然在 Stage 2 处卡住了。

其中 helloworld_x86_64-qemu-q35.bin 编译的基地址 0x10_0000 和 0x20_0000都试过，也都出错卡住了。

这个dd写入，应该和写入 /dev/disk3s1 (Bios Boot Partition ) 的位置是一样的，因此出错的现象也完全一样。

$ sudo dd if=./apps/helloworld/helloworld_x86_64-qemu-q35.bin of=/dev/disk3 bs=1 seek=17408 skip=0 count=61760
61760+0 records in
61760+0 records out
61760 bytes transferred in 0.143184 secs (431333 bytes/sec)

$ diskutil eject /dev/disk3
Disk /dev/disk3 ejected

最新进展：通过写入到 redox 启动 u盘的 /dev/disk3s1 位置，可以通过修改 ./modules/axhal/src/platform/x86_pc/multiboot.S

实现 vga 输出： ArceOS# （借助了 BIOS 的 int 0x10 调用）

代码可参考： https://github.com/limingth/arceos/tree/feature/vga/modules/axhal/src/platform/x86_pc/multiboot.S

$ sudo dd if=./apps/helloworld/helloworld_x86_64-qemu-q35.bin of=/dev/disk3s1
136+1 records in
136+1 records out
69952 bytes transferred in 0.068175 secs (1026064 bytes/sec)

通过 dd 命令写入 helloworld_x86_64-qemu-q35.bin

对比之前烧写 redox 的 u 盘 diskutil list 的返回信息
