Can DOS Access HPFS Drives?
It depends. eComStation allows the user to run genuine DOS in a virtual machine, by setting the DOS_STARTUP_DRIVE DOS Setting to either a floppy drive (A:), a DOS logical drive (C:) or a Virtual Machine Boot file (e.g. D:\VMBS\DOS5.VMB). This is done a) to support DOS applications that look for DOS data structures at specific locations, b) to support block-oriented device drivers (e.g. network drivers like Lantastic) or c) for software development and testing purposes. When running under eComStation, the DOS CONFIG.SYS should be edited to load the device driver FSFILTER.SYS. This acts like a network redirector, allowing all access to FAT drives to proceed normally but redirecting HPFS access through the eComStation kernel which is running in the background. However, when DOS is booted on the ‘bare metal’ of the machine, eComStation is no longer running, and FSFILTER.SYS has no effect. In this case, the user should obtain a shareware utility called AMOS310.ZIP or its equivalent. This pr
