DESCRIPTION:*Time is show in CET*\nSeaBIOS is generally used as CSM on QEMU
  to boot legacy OS with UEFI BIOS. However\, to achieve the same goal on p
 hysical hardware is not straightforward and we're facing challenges. We're
  able to overcome all these challenges and successfully boot legacy OS alm
 ost  from all kinds of medias(SATA\, NVMe\, PXE\, etc\,) by applying vario
 us extension and subtle changes on physical server computers. In this pres
 entation\, we'll highlight the changes and extensions we made on SeaBIOS. 
 For example\,  PCI rom BEV(e.g. iPXE) boot support\, 64bit MMIO support by
  BIOS provided SMM\, >128K pci oprom memory support\, boot event log sent 
 to BIOS(by SMI)\, VGA console to Serial console redirection\, map hard dri
 ves dynamically to support more than 2 hard drives\, timer/clock fix to su
 pport pci rom dispatching\, and so on.
