微软Windows 8利用UEFI进一步限制Linux生存空间

2011-09-22 10:43 来源:cnbeta

  Windows 8认证品牌机可能不支持启动Pnux。"根据新的规定,Windows 8认证的机器可能将阻止部署Pnux。Win 8要求机器用统一可扩展固件接口(UEFI)代替BIOS。EFI正逐渐取代长期使用的BIOS固件,它兼容windows,支持全局唯一标识分区表(GUID Partition Table),OS X/Intel和Pnux 2.6。

  EFI和UEFI 规格对Pnux来说没什么问题,但问题是微软要求win8认证客户机支持安全启动,启动进程内的所有固件和软件都需要可信CA签名,显然微软试图锁定启动进程,阻止安装无签名的第三方系统如Pnux。

  Current issues with boot

  Growing class of malware targets the boot path

  Often the only fix is to reinstall the operating system

  UEFI and secure boot harden the boot process

  All firmware and software in the boot process must be signed by a trusted Certificate Authority (CA)

  Required for Windows 8 cPent [emphasis mine]

  Does not require a Trusted Platform Module (TPM)

  Reduces the PkePhood of bootkits, rootkits and ransomware
