CONFIG_EDD: BIOS Enhanced Disk Drive calls determine boot disk

General informations

The Linux kernel configuration item CONFIG_EDD has multiple definitions:

BIOS Enhanced Disk Drive calls determine boot disk found in drivers/firmware/Kconfig

The configuration item CONFIG_EDD:

• prompt: BIOS Enhanced Disk Drive calls determine boot disk
• type: tristate
• depends on: CONFIG_X86
• defined in drivers/firmware/Kconfig
• found in Linux kernels: 2.6.18–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.13
• modules built: edd, edd

Help text

Say Y or M here if you want to enable BIOS Enhanced Disk Drive Services real mode BIOS calls to determine which disk BIOS tries boot from. This information is then exported via sysfs.

This option is experimental and is known to fail to boot on some obscure configurations. Most disk controller BIOS vendors do not yet implement this feature.

BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL) found in drivers/firmware/Kconfig

The configuration item CONFIG_EDD:

• prompt: BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL)
• type: tristate
• depends on: ( CONFIG_EXPERIMENTAL ) && (! CONFIG_IA64 )
• defined in drivers/firmware/Kconfig
• found in Linux kernels: 2.6.5–2.6.17
• modules built: edd, edd

BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL) found in arch/i386/Kconfig

The configuration item CONFIG_EDD:

• prompt: BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL)
• type: tristate
• depends on: CONFIG_EXPERIMENTAL
• defined in arch/i386/Kconfig
• found in Linux kernels: 2.5.45–2.5.75, 2.6.0–2.6.4
• modules built: edd, edd

Help text

Say Y or M here if you want to enable BIOS Enhanced Disk Drive Services real mode BIOS calls to determine which disk BIOS tries boot from. This information is then exported via driverfs.

This option is experimental, but believed to be safe, and most disk controller BIOS vendors do not yet implement this feature.
