Applied Engineering Vulcan IDE controller
|
||||
|
||||
Our copy of ROM version 1.4 will refuse any drive > 40 megs (top 2 bytes of # blocks >= 0x15b).
|
||||
Protection against field upgrades?
|
||||
|
||||
Vulcan Gold ROMs omit this protection but don't work with the version of the partitioner program
|
||||
we have.
