That's the amount of the max FAST RAM. KickStart is loaded into the other 512K, and it is not available to the user. -larry -- It is not possible to both understand and appreciate Intel CPUs. -D.Wolfskill +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

My friend recently bought an A3000 and upon setting it up and doing an avail, it showed the maximum FAST ram to be 512K! So we checked the chips and jumper settings and all seemed to be fine... also took a look at the startup-sequence to see if there were any descreptancies, but none found. Any help would be appreciated... -Dino Khoe -- ========================= MM MM OOOOO SSSSS HH HH Dr. Mosh | MMM MMM OO OO SS HHHHHH dksnsr@nmtsun.nmt.edu | MM M MM OO OO SSSSS HH HH Computer Science | MM MM OOOOO SSSSS HH HH

All Amiga 3000's shipped so far startup by reserving 512k of FAST RAM ro load the Kickstart image off disk to. When the ROM version (true final) of 2.0 is released, you will not have this happen. -Roger UUCP: {hplabs!hp-sdd ucsd nosc}!crash!pnet01!uzun ARPA: crash!pnet01!uzun@nosc.mil INET: uzun@pnet01.cts.com

On the EPROM versions of the 3000 (read that, any 3000 before 2.0
has been installed as a ROM) the Kickstart is loaded into memory and
executed from there. That makes it easy for you to update differing versions
of kickstart by simply putting a different disk in and telling the Amiga to
update kickstart. It does, however, use up the 512K that Kickstart uses.

A large number of people are having this same problem. PLEASE do not return the machine, it is not broken. Until the OS goes into ROM, it is loaded from disk into RAM. Since the OS takes up 512K, you will be short 512K until 2.0 is finally put into ROM. All developers should note this fact if you purchase an A3000. (We have had at least 2 such machines returned as broken.) -- -- Ken Farinsky - CATS - (215) 431-9421 - Commodore Business Machines uucp: ...{uunet,rutgers}!cbmvax!ken bix: kfarinsky

Many smileys of course. I am very impressed with my A3000 -- especially the fact that I can now watch TV with it on (where previously with my A500, I could not see many channels). >Ken Farinsky - CATS - (215) 431-9421 - Commodore Business Machines David Navas navas@sim.berkeley.edu "Excuse my ignorance, but I've been run over by my train of thought." -me

That makes it easy for you to update differing versions I just had the same unpleasant surprise as Mr. Khoe. I booted up a 2 Meg A3000 from the system so thoughtfully preloaded on the hard disk by C= and found the following : 866... bytes of graphics ram available out of 1 Meg = 1,048,576 bytes installed. So about 162,000 bytes of graphics memory are being used by the system. I assume this is for the system neucleus and the graphics screens. BUT only 220... bytes of other (fast) ram available out of 1 Meg fast ram installed ??? Mr. Seymores posting and one by Mr. Uszumn explain where 512K of the fast ram has disappeared to. The RAM: disk accounts for another 16K. But what's eating up the remaining 270K ?? On my 512K A1000, after loading up about 60K of my C directory to RAM: and getting rid of WB, Is still have about 280,000 bytes available in cli mode. Also the A3000 is one of those that has a 50 Meg hard disk. (Again praises to C= for their generosity). It comes with two partitions 5 megMEGeg. for SYS: and 41 Meg for WWRK: But where are the remaining 5 or so Megs?? On my IBM PS/2 the 40 Meg. hard drive has 40 Meg. available for me to use. I hope at least that the 4 Meg. of expansion ram due to be added to the A3000 will all be available. ----------------------------------------------- Reply-To: Rostyslaw Jarema Lewyckyj urjlew@ecsvax.UUCP , urjlew@unc.bitnet or urjlew@uncvm1.acs.unc.edu (ARPA,SURA,NSF etc. internet) tel.

I ran into the same situation the first time I upgraded a 3000. You see, the first time I did it, it was the store's demo unit and the unit showed 2M Chip total and 1M Fast. However, when I added memory to a recent RELEASE 3000 I only got 512K Fast and was confused for a while. Then a quick call to tech support cleared things up. With the current 3000's the memory that is used to load KickStart doesn't even show up to the system. This is why you only see 512K, the other 512 is KickStart. I also noticed that these 3000's have a little daughter board in the EPROM sockets holding the boot chips.
