It appears that the SMBIOS table is bogus on machine B. Do a "dmidecode" on machine B and search for IPMI to see the table entry and be sure. > Do SMBIOS and ACPI both exist in the BIOS at the same time? > Yes, they do. The IPMI driver prefers SMBIOS because it carries the slave address. That's not available in ACPI. -corey ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
