More memory on unexpanded A600 booting from CF0: - Page 2

However,
I reverted partially to the RAM: settings, and it works again. I have 670KB free, more or less.

I presume that "normal" means PAL 640x256, 4/8 colours, which isn't really a lot required for the screen.

Do you have anything in the user-startup or WBStartup?

Yes, 640x256 4 colors. Yesterday I set it to 2, and got some KB more.
If I boot it in WinUAE I get 200KB more free RAM, probably because I boot from the CF directly (avoiding to boot from the floppy and load cardreset, cardpatch, movesys etc.). Alexh is right, I should/will buy an internal IDE/CF adapter and/or a memory expansion. I don't know if it's worth it... perhaps I'll get an A1200.

About the user-startup, it only includes a path for Directory Opus.
No strange commands...
In WBStartup I think I have nothing special. It's a plain normal installation of WB 2.1.

However, the problem arises from IPrefs, and I don't know why.

Cardreset and cardpatch are A1200 programs. Not required for A600 although I doubt that will save you any RAM.

Do not forget that A1200 trapdoor RAM cards are more expensive than A600 ones. You could consider getting a PCMCIA SRAM card?

Are you sure? It wouldn't seem so...
In the documentation is written "Requires: Kickstart 37.300+, A600/A1200" and "Requires: Kickstart 37.299+, A600/A1200".
See on Aminet:

Ok, but they are usually much bigger! 4/8MB RAM, instead of a mere 1MB...

Hi,
I tried booting without cardreset and cardpatch (gained 2KB only

). It seems to boot without problems.
Perhaps they are needed more if the PCMCIA card is hot-extracted/hot-inserted? (I never do it, since it's now my equivalent of DH0:

)

Hope the system is stable without them

Another issue I don't understand is WHY yesterday I got 676KB RAM free, and this morning, with the same configuration, I got 664KB RAM free

Get a trapdoor expansion. 646KB of RAM out of a beefied workbench is not that bad.
If you don';t use them, skipping all the preferences loading will save you loads of memory (ie. skip all the ENVARC and iPrefs shit). Look at this startup I just thought of for you:

Code:

AddBuffers >NIL: DF0: 15
FailAt 21
Add44k

MakeDir RAM:T RAM:ENV 
Assign >NIL: ENV: RAM:ENV
Assign >NIL: T: RAM:T

IF NOT EXISTS SYS:Fonts
  Assign FONTS:
EndIF

Path >NIL: E: C: SYS:Utilities SYS:Rexxc SYS:System S: SYS:Prefs SYS:WBStartup SYS:Tools SYS:Tools/Commodities

IF EXISTS S:User-Startup
  Execute S:User-Startup
EndIF

LoadWB
AddBuffers >NIL: E: -999
AddBuffers >NIL: DF0: -999
EndCLI >NIL:

I don't need fancy shit most of the time, and I am fine with a 4 or 2 colour workbench, i won't be looking at it too much and it saves me RAM. You should get the Add44k program to downgrade your bittplanes to 4 or 2 colours.

It won't look pretty, but you should get at least 730+KB of RAM.

Also, check your s:user-startup file, you may hav something there that ats RAM up too.

Supamax · 18 January 2009, 00:42

Hi Akira,

if I want to reduce bitplanes, I *have* to load IPrefs... there's no way out, because IPrefs gives me the error I described before

Furthermore, if I load AddxxK (44 or 21 or 36 or whatever) I can't use WB anymore...

I bought a CF/IDE adapter, so I will connect another CF internally. This way I will not boot from floppy and I will have more RAM (around 700..800KB).

I know this is not a solution, it's a shortcut

Have you any ideas why Intuition gives me the error (see previous posts) ??

No, Add44k will reduce bitplanes one at a time. Try it.

Wrong, I used Workbench without problems with this. Maybe you have a wrong/different command than I do.

You can also disable the DF0 device at bootup for some extra RAM.

As I said, don't use iPrefs at all.
This error, I don't know. Try to see the protection bits of the file screenmode.prefs. set them to 'rwed'

My recommendation is to NOT use iPrefs. Looks shittier but works better. Look at my startup-sequence. Try it !

Have you a link to it?
It's very difficult to find (I tried for a while, days ago, but didn't find it).

Amiga1992 · 18 January 2009, 01:16

I have it in my A600.
If you don't find it in a while, I'll post it back in a monh (I'll get to my 600 in one month's time)
I used it for years

I found this one right now:
http://adfsender.stoeggl.com/utility/add21k_44k.zip

I'll check it.

Amiga1992 · 18 January 2009, 06:46

NOt sure if that's mine. As I said, I can only check with my Amiga!

I'll eagerly wait

Amiga1992 · 05 February 2009, 07:10

My friend, tomorrow I will inspect my A600. I just got to meet it

I'll get my hard drive backed up again and will share my files with you.

Supamax · 05 February 2009, 17:28

Thanks Akira

.

In the meantime (following alexh's advice) I got an internal CF/IDE adapter, which I formatted (FFS) and prepared with OS 2.1.
Now I'm booting straight from it.
If I boot from it with no CF/PCMCIA inserted, I get around 750 KB RAM.
But when I insert the external CF (FAT-formatted), memory drops down to 630..640 KB. I suppose it's due to the FAT (or PCMCIA) management.

Amiga1992 · 19 February 2009, 00:04

Hey my friend,

Find attached the files I use in my A600.

execute ADD44k a couple of times and it will reduce to 2 or 1 bitplane.

I'll post you my startup sequence later.

cheers!

Supamax · 19 February 2009, 00:16

Thankx mate!
