| Summary | 0000519: Improve Hercules DASD image reporting | ||||
| Description | The detection and reporting of Hercules emulated DASD images can be improved to report more types and what type of compression is used. In addition, the reporting of DASD types 3380 and 3390 is incorrect: they're reported as 33FFFFFF80 and 33FFFFFF90. The attached patch makes these improvements. | ||||
