Title: I lose 600kb of RAM on A1000...
Post by: arttu80 on January 30, 2011, 01:56:31 PM

Everytime I boot it from A590 HDD, which is equipped with 2MB RAM and 2Gb disk, Workbench shows about 1.9Mb after booting. When I disable HD and boot from floppy it's more than 2.3Mb available.

So, I've been told it's my ancient File System v.36.3, BUT can it be upgraded and to what? I run kickstart 1.3 and A1000 w/256kb expansion, as one may guess.

I tried Aminet, but couldn't find suitable FFS for Kick 1.3.

I assume that most of that memory is being used as memory buffers.  You need the memory buffers.

Please goto shell and type:

Code: [Select]

addbuffers dh0:
and tell us what it says.

2.3mb-1.9mb=400kb ;)

How many partitions is your hard drive divided up into?

A drive with a lot of partitions eats more ram than a drive with just 1 big partition.

There's also the question of what else is in your S:startup-sequence on your HD.
When you boot from floppy, it's usually a smaller install with less "things" than a typical HD boot.

This is quite normal. The HD system takes some, that you cannot control. Then there are buffers that you can control.
All in all that's a small price to pay....

I have checked for added buffers using HDInstTools program, so I have 30 buffers on dh0 and 30 on dh1. Will this eat up 400kb?

Also I have very stock WB1.3 and direct copy of startup-sequence from floppy disk, so not very much addons there.

I'm pretty sure the HDtools program or whatever lets you set buffers separately.

Yes I know.
