Welcome to Oldschooldaw.com! (Online since 2014) serving vintage computers worldwide! this is our NEW WEBHOST as we've moved from our OLD GODADDY to a brand new server location to start off 2026. thanks to Godaddy for hosting the site for 11 years and a big thank you to IONOS.COM for the great pricing going forward! this site exists as a resource for historical archival of information + file resources neccessary to make use of vintage computer hardware + vintage music composition software that runs on those old platforms. conceived conceptually by Chris Nova to address the problem of  missing information + missing chronological references caused due to this information slightly predating the creation of the modern internet, much of the information here has been sourced from magazines + books as well as scraped from other websites that have since gone offline and wont be coming back.

ESP EFI boot0af (GPT) vs boot0ss (MBR)
« on: December 13, 2023, 12:16:35 AM »
boot0af
Used for BIOS booting on GPT partition.
boot0af (boot0 Active First) bootloader try to boot the active partition defined in MBR. If there is no active partition, it will try to boot the first EFI/FAT32/HFS partition (defined in the MBR and then the GPT) with a valid PBR signature.

boot0ss
Used for BIOS booting on MBR partition.
boot0ss (boot0 Signature Scanning) bootloader try to boot the first EFI/FAT32/HFS partition (defined in the MBR and then the GPT) with a valid PBR signature. If no partition is found it will try to boot the active partition defined in MBR.
