I think I have found an ATA support abuse in the recent x86 ISO

  • The problem is - I have ASUS P4C800 motherboard and was trying to install the latest version of Pfsense. Installation works just fine, but when I'm trying to boot the installation I'm having errors like : error 1 lba XXXXXXXXXX. The Allmighty says it is the incompatibility arising from ATA misbehaving. Seems like the motherboard uses "workaround" mechanism but Pfsense supplies the 48 bit LBA numbers directly.

  • Confirmed the problem .This is really the chipset limitation of which BTX loader is unaware. The workaround solution was to switch SATA into RAID JBOD. Thankfully the mainboard supports this.
