"Good" News to the people with a problem something like this:
"Sysinfo said my hard disk device drivers were in Slow, and not in Fast RAM,
and told me to move them to Fast RAM first thing."
I don't have "The" solution for this, but want to tell you a story:
I started one of these threads some weeks ago, and got only questions from
other people, who wanted to know if I had got any positive advice.
The only "positive" advice I received was about changing it in the mountlist;
I posted this, but was told by several, that this would not work on autoboot-
ing FFS systems(like my gvp). It may work on some, though.
So, I forgot about it. But three days ago, a friend of mine and myself left
our computers at a Repair center, to have them move several things for us.
Amongst the things they did, was put my 2.5 meg internal RAM in his A500,
then upgrade my agnus so I'd have 1meg chipram, and put 2 meg SIMM in my GVP.
I bought myself 1/2 meg internal RAM with clock, and put that in too.
And when I got home, SYSINFO TOLD ME MY DEVICE DRIVERS WERE IN FAST RAM NOW!
So to sum up:
- I don't know what of this caused it, but I know they were in slow
ram before, and in fast ram after.
- My system is an A500 with 1.3 Kickstart,and new agnus(1MB chip).
An Impact Series II harddisk eq. with 2MB simm
and a 1/2 meg with clock internally in the 500.
- I don't know what this slow/fast ram thing is good/bad for(speaking of
harddisks). I did not seem to miss any of the 512 k chip mem before(?).
- I don't know if one could reformat/use faaastpreepsss to change this
slow/fast thing(like changing the mountlist on previous/elder systems).
So if someone with any brains had any idea what this is all about(like
got a clue from my example) and would explain to the rest of the few of us
interested in this, this posting would have served its purpose.

Well, this is a *only* a guess. Probably what caused the hardrive driver to move from slow ram to fast ram was the installation of the 1 meg Agnes chip. According to the docs of my hardrive (a hardframe), systems with the old Agnes chip will always get slow (pseudo chip) memory for the driver, regardless of how much expansion memory there is. When you install the 1 meg Agnes you kill all the pseudo chip memory. The driver's new default location is expansion RAM. - Chris =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Christian Castor - cac5961@usl.edu or chris@usl.edu - CIS: 73030,2734 Plink: ChrisC - (318)232-2045 - Snail: PO Box 43402,Lafayette LA 70504 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

Slow RAM is RAM on the motherboard that is not being used as Chip RAM. At first you had 512k chip / 512k slow RAM. When you upgraded to 1M chip RAM, you no longer had any slow RAM since all of the motherboard memory was being used as chip RAM. The RAM in your expansion card is fast RAM.

Maybe like this: Chip RAM: RAM that can be used by custom chips as well as CPU Slow RAM: RAM that can't be used by custom chips, but is as slow as chip ram. Fast RAM: RAM only accessable by CPU. Anyway, slow RAM occurs when you have an Agnus which can access 1MB chip, but is shipped with 0.5Mb. (ie. A500r6 or above), (eg. 8372 agnus in A500r6A) but have an A501 expansion. The extra 0.5MB is slow ram 'cause it can't be accessed as chip ram w/o hardware mods. >-- >Jerry Shea | INET: jerrys@bunker.shel.isc-br.com >ISC-Bunker Ramo, An Olivetti Company | UUCP: uunet!bunker!jerrys >2 Enterprise Drive | BIX: jshea >Shelton, CT 06484 USA | Phone: (203) 337-1646 -- ____________________________________________________________________________ | | | | Luke Mewburn (Zak) | This side for lease... | | s902113@minyos.xx.rmit.oz.au | (No disclaimer, can't afford it:-) |

First of all if you put in a 2meg SIMM and the A501 or clone you must have had only 512K, all chip to begin with. But I'll assume you had at least one meg, with 512K chip and 512K slow-fast. Note, that's slow fast RAM. It still has problems like chip RAM because of bus contention. However if you add fast RAM (real fast RAM) and change your slow fast to chip RAM, then your drivers go into the real fast ram. Normally FastMemFirst sets the fast and slow fast RAM to 0 priority, and the chip to -10 (on mine anyway), so fast and slow fast have the same chance of being used. On mine, at least 130K slow fast is used after booting and maybe 10-20K fast. So my drivers are also in slow. To get your drivers in fast, I guess you'd need the 1 meg chip option or somehow set slow fast to -5 pri or something like that. The above is what I've been able to come up with, it might not be totally correct, but it explains the problems. Amiga is die beste! 'n IBM is 'n rekenaar? Die Mac is net 'n vrot appel!
