What is the difference between these?
This release contains five files. You can choose one of these files
depends on your devices. Most modern devices should be able to run the
64-bit ISO. For older devices with legacy BIOS, you may try the 32-bit
64-bit ISO: android-x86_64-9.0-rc2.iso
32-bit ISO: android-x86-9.0-rc2.iso
64-bit rpm: android-x86-9.0-rc2.x86_64.rpm
32-bit rpm: android-x86-9.0-rc2.i686.rpm
64-bit ISO with kernel 4.9: android-x86_64-9.0-rc2-k49.iso
Recommended for VMware users
To use an ISO file, Linux users could just dump it into a usb drive to
create a bootable usb stick like:
dd if=android-x86_64-9.0-rc2.iso of=/dev/sdX
/dev/sdX is the device name of your usb drive.
Windows users can use the tool Win32 Disk Imager to create a
bootable usb stick.
Please read this page about how to install it to the device.
Except the traditional ISO files, we also package android-x86 files
into a Linux package rpm. It allows Linux users to easily install the
release into an existing Linux device with a standalone ext4 root
