If hard disk contains a recursive extended partition with wrong slice offset specification (prepared by another OS), the disk opening may cause the reading of a sector beyond hard disk limit. Such request is handled by BIOS for a some seconds, and been repeated multiple times, this situation dramatically delay a boot process. >Fix: Add a check of the requested sector to be in hard disk limit's inside the bd_read() function in the biosdisk.c, and do not perform BIOS read if the check fails. >Release-Note: >Audit-Trail: >Unformatted:
