Abstract
The present disclosure includes methods, devices, and systems for booting in systems having devices coupled in a chained configuration. One or more embodiments include a host and a number of devices coupled to the host in a chained configuration, wherein at least one of the number of devices is a bootable device and the at least one bootable device is not directly coupled to the host.
Claims23
A device, comprising:
- boot code, wherein:
- the device is configured to be coupled to a host in a chained configuration of devices;
- and
- the device is configured to send the boot code to the host through the chained configuration without receiving a boot command from the host.
1 more element
A method for operating a device, comprising:
- sending, via the device, boot code to a host without receiving a boot command from the host;
- wherein the device is coupled to the host via a number of additional devices in a chained configuration.
A system, comprising:
- a host;
- and
- a number of devices coupled to the host in a chained configuration, wherein:
- at least one of the number of devices is a bootable device;
- and
- the host is aware of which of the number of devices is the at least one bootable device before sending a boot command to any of the number of devices.
3 more elements
A method for operating a system, comprising:
- sending a boot command from a host to a number of devices coupled to the host in a chained configuration, wherein:
- at least one of the number of devices includes boot code for the system;
- and
- the host is aware of which of the number of devices include the boot code before sending the boot command.
1 more element
A system, comprising:
- a host;
- and
- a number of memory devices coupled to the host in a chained configuration, wherein:
- at least one of the number of memory devices is a bootable memory device configured to send boot code to the host without receiving a boot command from the host;
- and
- the at least one bootable memory devices is not directly coupled to the host.
