differences in ram consuming winuae vs real 1200
Hello, i have begun a project with a involve a 1200 with hd, but on desktop original case. I have made a configuration file on winuae just exactly with the same as the real 1200, so i can work on certain things without messing on the real hard and os(por commodity purposes in case something goes wrong).
The main problem is that having the winuae config and the real 1200 the same specs, when booting with them, each one has different chip ram consum. The winuae install is the same as the real 1200(both are a plain 2mb chip unexpanded systems), but the winuae one when booted has approx. 1.800.000 kb of memory, while the real has approx. 1.340.000 kb of memory. That is a huge difference, and in each one, are the same install, bare 3.1 system and same whdload games. What's going on? How is it possible? Who lies, winuae or the real miggy? Hope someone has the answer for that, and thanks in advance. |

Harddrive buffers? Directory harddrive emulation uses very little Amiga-side memory.

I thought on that, seems that the real hd buffers consumes nearly 300 kb of chip?!?!?
I will still keep investigating it. Thanks for the reply. |

You say, you want to created a WinUAE config which is identical to your real Amiga setup. But if you use HDD directories, this is not at all true. You should use a HDF in RDB mode or a real HDD, then you'll get similar results. But only if you use the same settings in HDToolbox as you used on your real Amiga.
300kb means 600 buffers with 512 bytes block size. Or 300 buffers with 1024 bytes block size. Did you set so many buffers ? Or do you have so many partitions ? |

I have a 800 mb drive partitioned into 4 partitions. Is there the problem?.

There is no problem. It was only a question. Or rather a hint where you have to search the memory. Check with HDToolbox how many buffers each partition has an which block size it uses. Then you can calculate the memory consumption.
If you create a similar HDD setup in WinUAE it will need the same amount of memory. |

So if i reduce the buffer on partitions i could get less ram consumption?
I will take a look. |

I read an article on a past Amiga magazine and it suggested to do not create no more of 2 partitions because they get a minimum RAM (64K ?) indipendently their dimensions plus a quantity of RAM according to their dimensions (I think for buffer as you can see in HDToolBox).
You could create drawers as you want and give them the name and the icon image of the partitions, then move them to desktop; obviously they are not partitions but they seem and often work like them. |

You dont happen to use SFS as filesystem on the real Amiga? This filesystem uses a lot of ram, apart from the buffers. A lot is in this case equal a couple of hundred kiloBytes.
