Hardware/Software (Emulator) Requirements

Minimum Requirements (BIOS)

• CPU Currently any x86_64 proccessor
• RAM 75 MB
• Storage Nothing required yet.
• Graphics Only Framebuffer.

Minimum Requirements (UEFI)

• CPU Currently any x86_64 proccessor
• RAM 170 MB
• Storage Nothing required yet.
• Graphics Only Framebuffer.

Recommended Requirements (BIOS)

• CPU Currently any x86_64 proccessor
• RAM 128 MB
• Storage Nothing required yet.
• Graphics Integrated Graphics

Recommended Requirements (UEFI)

• CPU Currently any x86_64 proccessor
• RAM 256 MB
• Storage Nothing required yet.
• Graphics Integrated Graphics

Booting to real machine

This operating system is real machine bootable and tested under the following circumstances:

Boot Disk information:

• Using 32 GB Pendrive
• GPT Disk (MBR Also works)
• Both BIOS / UEFI supported
• Ventoy loaded
• FrostWing.iso in the root directory

[!IMPORTANT] It is recommended to use Ventoy because you will not have the risk of flashing and failing of USB-Drives
