https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=176748 --- Comment #3 from Arrigo Marchiori <ardovm@yahoo.it> --- Hello, after some investigation, I could confirm that yes, the BIOS is broken. However, the vendor of the embedded PC's I am using, is still applying the old and broken BIOS to recent units. I only upgraded the FreeBSD sources last week, and the patch seems not to be effective any more, when booting from (recent) USB pen drives. For some weird reasons, the sector size of such USB sticks is returned as 12022 bytes or something like that, that is not correct. Would it be advisable to add some more safety checks, such as: - sectors must be non-zero; - sector_size must be non-zero; - sector_size must be a multiple of 512? Such a check enables my terminals to boot again. -- You are receiving this mail because: You are the assignee for the bug.
