Issue with BetterWB

[Oldsmobile_Mike]

Here  is my question to this! I ordered Denise 8373 or something like that  from eBay. Can I just easily replace my Denise with this new Denise from  eBay without any difficulty? Would I literally have ECS instead of OCS?  Would I literally be able now to have the ability to switch between  PAL/NTSC when this version is currently disabled now? Will I be able to  switch between ECS/OCS when I hold down the two mouse button if I  install this new chip? Would I have increased color in workbench if I  install this chip?

My A500 is revision 5 it can only do 1 MB CHIP  RAM maximum, I am intending to buy the 512K RAM trap door to install it  in my A500 in the future

That's a lot of questions.  

You should do the 1MB chip mem mod if you plan on using enhanced or high res screenmodes.  8371 only supports 512K, so you'll need to pull that out (or push it out from the bottom, PLCC chips are a pain-in-the-arse) and replace it with an 8372.  After that there's a couple ways, including soldering a few spots on the motherboard, or doubling up the chips in their existing spots, etc.  What you decide depends on motherboard version and technical proficiency.  Personally I recommend the version of the mod that converts the 512K in the trapdoor slot into chip ram.

You can also add a "Megachip" adapter after that, which would use (typically) an 8375 Agnus, and give you 2MB.

ECS screenmodes ain't much to write home about, but me personally, I like 'em, and I like having my Amiga's as "up-to-date as possible", especially since you can buy those chips all day long for under $20.

You start doing these other upgrades, you might as well look at the Indivision ECS.  For under $100 USD this will give you scandoubled output on every screen mode, as well as allow you to use things like the SuperPlus 800x600x16 colors mode.  Make sure you upgrade to 1.10 firmware.  Obviously you'll want an accelerator to use that screenmode.  

Early Startup control ("holding down the two mouse buttons"), you've already got that.  That's part of 3.1.  You do have an actual 3.1 ROM, right?  If not, go buy one.  Just do it.  It's under $20.  Don't listen to these cheapskates who say not to.  Then yes, you'll be able to hold down both mouse buttons and switch screenmodes.  

Like I said, I like ECS, and feeling like my system is "more modern".  But you might want to read what the actual differences are before you start waiving your hat in excitement about it.

1) I need to upgrade AGNUS to get 1 MB CHIP RAM?  
2) You said my A500 revision 5 can actually see 2 MB CHIP RAM by having an adapter? Are you saying with this adapter I can get the mega chip agnus and have 2 MB CHIP RAM?
3) Is there an actual 1.50 MB trapdoor RAM upgrade?
4) If the answer is no then is there real point in doing this! My A500 motherboard's already filled with RAM to give 512 KB CHIP RAM in default and there is no space to solder more RAM chips.
5) Do I really, really, really, really need to do soldiering, putting wires left and right to do this upgrade? Remember I have revision 5.
6) If the answer no for soldiering and all I have to do is remove the chips and replace them with these chips I might as will do all of that just for the feeling that I have the choice available, where do I find the megachip adapter? How hard to find them? How expensive to buy them? How difficult in installing them?  
7) Already coming by mail the super denise can I install it by itself with my normal OCS Agnus that only sees 512 KB or it will fail and need to do the rest of the upgrades?  
I want to buy the 512 RAM trapdoor and place it as chip RAM and not as FAST ram but are you saying that cannot be done with my current agnus until I do the upgrade?

1 - YES - read the first link in my comment
2 - YES - read the second link in my comment
3 - Not one that will give you actual chip memory
4 - One of the versions of the mod puts more chips on top of the existing chips.  But I recommend the trapdoor conversion
5 - I've never owned a Rev. 5.  I've owned several Rev. 6's.  With a Rev. 6 it's just a couple solder pads that need to be changed.  Your mileage may vary.
6 - The Megachip pops in after you remove the existing Agnus.  Read the second link in my comment.  They usually run around $100 on Ebay, they show up fairly regularly.
7 - It should work fine, but 512K of chip mem really isn't enough for most tasks (besides some light, classic gaming)
8 - Correct

Just to throw this out there, I vaguely, vaguely recall hearing that with an ACA500 there was some kind of hack that it could do to provide 2MB of chip mem, but even if such a hack does exist (google it), I wouldn't trust it as far as I could throw it.

I already purchased the ecs indivisions but in kickstart 3.1 it fails, the graphics becomes jibberish and non functional!! This is why I am sellling it...it is not working with my A500 and because I removed my denise soooo much the pins are bending horribly but it stil works so I ordered another denise in fear this one will be ruined. I just discovered i ordered a super denise and decided to go through this upgrade since I really want 1 MB CHIP RAM and not 512 KB chip RAM

I just saw your edited comment.

The Indivision ECS works fine with Kickstart 3.1.  You do have an actual ROM, right?  Not some mapped thing?  I'd suggest you have a grounding problem if yours wasn't working right, or possibly a defective unit.

The Denise has nothing to do with the amount of Chip memory.  That's controlled by Agnus.

The only question I need to ask this...in the link it says it is motherboard revision 6 and up. Do I need to do any soldering? Is there someone out there can confirm if I need to do some wiring and soldering? If the answer is no, then I can just buy these chips without worry and do the upgrades easily...as long it is a matter of removing chips from socket and replacing them with better ones.

Which chip are you talking about?

Read pages 9-11 of this manual, it specifically mentions the Rev. 5 motherboard:

http://amiga.resource.cx/manual/MegAChip.pdf

Even though you are not installing the Megachip (at this time), you will still need to do the required mods to convert your 512K on motherboard + 512K in trapdoor slot into 1MB of chip mem.  Oh, and also you will need an Agnus that supports 1MB.  

[Oldsmobile_Mike]

I get the feeling you are kind of new at this.  For what reason(s) specifically do you want the additional chip memory?

Amiga's  are definitely fun "hardware hacking" platforms, and this is a very  common and easy mod.  Hence why there's different versions of it out  there.

All good reasons.  So you're not just using it for games.  

The Agnus chip just "pops" out.  You need a PLCC puller tool (also available on ebay, or any electronics supply place).  They can be tricky though, so as a backup Commodore "provided" two holes in the bottom of the socket, straight through the board.  In other words, you can remove the motherboard and just push the chip out from the bottom.

You didn't post your location so it would be hard for someone "where you live" to respond.    Worst case scenerio, send your system to someone like AmigaKit, they should be able to do the work.
