Hello,
Does any of the Linux OS flavors support booting from the 4K sector
(advanced format) drive in legacy BIOS mode (MBR partitioning scheme) ?
Thanks & Regards,
Mahesh

That depends on boot loader, not Linux I think.
Linux has support for 4k sector drive, but if the boot loader
doesn't, it can't fetch the kernel into memory and load Linux.
Legacy grub makes use of BIOS interrupt service and thus shouldn't
be able to support 4k sector drive, I don't know the status of grub2.
Thanks,
Aaron

Hello,
It also depends on HBA BIOS driver, which need to properly handle 4k
sector. Linux kernel do support 4k sector.
