BIOS/MBR vs UEFI/GPT install
My computer allows me to boot from USB disk prepared with minirootXX.iso in two ways, Legacy and EFI. I used Legacy until now with BIOS/MBR to install and use OpenBSD. I tried UEFI/GPT but things went wrong and I was not able to boot OpenBSD's kernel after install. Is there any penalty using BIOS/MBR versus UEFI/GPT? Are there any extra steps to be taken if one uses UEFI/GPT other than dd minirootXX.iso to an USB disk? Thank you.
