SVBus
SVBus Virtual SCSI Host Adapter for GRUB4DOS
Today we present a new virtual SCSI driver for use with GRUB4DOS named SVBus. The driver is used like WinVBlock and FiraDisk to access GRUB4DOS mapped drives from Windows. At the moment VHD file disk and RAM boot are supported. The supported OS platforms are Windows 2000 up to the newest Windows 10 on x86 and x64 architectures.

Many thanks and much respect go out to the authors of WinAoE, WinVBlock (Shao Miller), FiraDisk (Panot Joonkhiaw), DSEFix and of course to the reboot community, which made the VHD RAM and disk boots in Windows possible!
