[PATCH 1/2] disk: read up to 63 sectors in LBA mode

There's no need to obey CHS layout restrictions for LBA reads on LBA disks, it only slows down booting process. See: https://lists.gnu.org/archive/html/grub-devel/2023-07/msg1.html --- grub-core/disk/i386/pc/biosdisk.c | 5 - include/grub/disk.h | 3 +++ 2 files changed, 7 i

[PATCH 0/2] disk: use maximum number of sectors for LBA

GRUB2 limits number of sectors read at once in LBA mode to the number reported in CHS disk geometry by BIOS. This is unnecessary, as IBM/MS INT13 Extensions allows reading up to 127 sectors in a single call. This fixes greatly increased boot times on WYSE C10LE x86 thin client with Phoenix bios.

Probably. If you could share with me a link to the binary/package which fails I could double check all symbols are in place. Daniel Hi Daniel, https://mirror.f4st.host/archlinux/core/os/x86_64/grub-2%3A2.06.r591.g6425c12cd-1-x86_64.pkg.tar.zst Tobias -- Tobias Powalowski Arch Linux Developer
