help to make OWN "ram:" device

[Ilwrath]

You're welcome... Let us know how it works out for you.  We really should write this up into a FULL tutorial, as the topic of writing ADFs for Amiga 500's comes up every few months.  (And we've kinda given inconsistant answers over time, because it is such an in-depth procedure...)

ps: hey where do you usually buy your amiga devices ? just curious ! (as always :-) )

I'm in the US...  I've worked with our own "redrumloa" and his Anachronism Industries, as well as the old stand-by of Software Hut, and been quite satisfied.  Mostly, lately, though, I just pick up odds and ends here and there that add to my collection.  (random finds, saving Amigas from scrapheaps, etc...)  Heck, I'VE probably got as much inventory as some dealers...  ;-)

Yes, I'll post the outcome tomorrow, just hope it'll work, not too optimistic though !  :oops:

Well daaaa !! :-o , need you REALLY tell me that echo just writes text to the screen ? Cheeezes, I wasnt looking for an description on what "echo" is and how it works  :-D , I wondered if those few lines BEFORE it were enough for a functioning ram-handler !

That's properbly why I putted the BTW letters in front of my reply to you. To inform you if you didn't know it
And I'm sorry I couldn't see the lines you where talking about anywhere in your posts...

Oh, I cant post you my startup-, I'm not at home.

Too bad I guess...

[GreatLor]

Darn, it worked, but it gave me 941k  :pissed:
f.u.c.k  :lol: , I just need some 19k more, GRRRR ...
yepp, destiny is truely a funny shot !

[Ilwrath]

Hmm....  Why not try add21k or add36k?  They free up extra chip ram by stripping the extra screen bitplane (reducing you to two colors).  Also, delete "L:system-configuration" from your boot floppy.

I found an aminet link to add36k under util/misc.

Maybe it'll put you over the top!

Are lzh-files extracted with lha ? in that case lets see what the baby can give me ?

You know, I was also wondering if I could remove 1 or 2 dos-librarys that are in the RAM and who do not get accessed unless called from specific dos-commands, I thought if it would be possible to do it by calling the FreeMem-routine in exec.library or are these libs untouchable ?

"lha" should be able to extract the older lzh files.  If not, "lharc" can.   Wacky old WB1.3 programs.  :-)

If you're not running a s:startup-sequence, the only libs in ram should be things in use.  Most likely, the libs you're seeing are part of your kickstart ROM, and can't really be freed.  ;-)

Got the message !  :-)

In the good old days, you could get some more memory by freeing one bitplane of the initial workbench screen using a command called Add21K (I only found ftp://de.aminet.net/pub/aminet/util/misc/add36k.lzh on Aminet, but the original Add21K seems to be found in ftp://de.aminet.net/pub/aminet/demo/disk/mlw_cr.lha aswell). And on Kick2.0 and higher you can also do an

AddBuffers DF0: -999

to get some more memory. Hope this helps.

What exactly does that do? Does it just remove all buffers?

[Thomas]

It removes 999 buffers from DF0. Let's calculate. It has 10 buffers by default, in Startup-Sequence another 20 are added, then 999 are removed, so -969 are remaining. I suppose the addbuffers command has some kind of range check built in, probably the minumim required remains. Probably 5 or 1 or something like that.

One buffer needs the same amount of memory as the block size of the disk. So 10 buffers takes you 5 kb of memory (512 bytes per block).

It seems my missfortune has NO PLANS of taking a vecation, guess what now, ok, I go and buy 10 "verbatim" disks, and amiga-format them in the amiga, then I unpack an lha file and copy to the disk, I insert that disk and try to "dir", but no, "not a dos-disk in df0:", I format them again with other formatting tools, it's still "not a dos disk in df0:", now, have anyone ever experienced these "verbatim" disks ?

[Noster]

Hi

Verbatim disks have been very good disks, I've liked to use them and have no bad experience.

To your problem: Try to load the Workbench, open a CLI and enter "Format drive df0: name foo". This should format the disk in the floppy drive. If any error occurs, this tool will notify you. If it works to format, the disk is Ok and should occur on your Workbench screen.

Nope, it didnt work the format command says "bad sector" or something like it, this is REALLY weird !!!  :pissed:

Did none of your disk could be formated ?
Maybe your disk drive is misfunctional ? (Do the problems ever end for you ?? ;-))
