If the total sectors exceeds 127Gb this is not possible, but normal simh disks are smaller and the largest user settable size via RAUSER is just under 1Tb. The excessive size case (>127Gb) will have a CHS of 0xFFFF10FF. simh never cares about the CHS Disk Geometry value in the VHD footer data structure, but other applications which do care about the CHS value using the previously incorrect value as the capacity of the disk even though the Current Size indicated in the footer may have been larger.
Open SIMH machine simulator
This is the codebase of SIMH, a framework and collection of computer system simulators.
SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.
The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.
