Quote from: JonB on 16:17, 07 March 17OK @arnoldemu, I will try these values.The other question is about the 2.2 BIOS. It seems rather low in memory at AD00h. When I did MOVCPM it tried to create a 48k CP/M system, is that the default? I'd have to move this down to 43k to get the full drive access, which I think is a bit low...How big is the CP/M 2.2 TPA? Must be titchy - and what is the upper RAM all getting used for, if the BIOS is actually in ROM? What does the CP/M 2.2 memory map really look like?A quick look at one of your disassemblies (AMSDOS.COM for 2.2) shows some memory paging going on. This doesn't happen in 6128 CP/M 2.2 normally, I hope!
Quote from: FloppySoftware on 23:41, 07 March 17I think you can't use MOVCPM to construct another version of Amstrad CP/M 2.2.
QuoteIn CP/M 3 you could use CP/M RSXs (not the Amsdos ones) to add new functionalities or patches to the BDOS or BIOS, but in CP/M 2 is trickiest because it does not have (official) support for RSXs.
