Benefit of 3.9 roms?

[desantii]

What is actually the benefit of 3.9 roms vs running softkick type tool? I want to experiment in making a rom and then burning in a eprom but want to understand the benefit.

If someone has a 3.9 file thye can send that would be awsome so taht I can play with it while I make my own.

[PeterK]

There is no universal 3.9 ROM that fits to everybody's system requirements.

But you can extract all ROM modules from your kickstart and from the OS 3.9 ROM-Update file and build your own custom ROM with the tools ROMSplit and Remus: http://www.doobreynet.co.uk/beta/index.html

Different Hardware = different Roms

1. A500/600/2000 (also A1000/PhoenixA1000/GBA1000) / 68000 code
2. A3000 / 020+ & FPU-code (FPU-code only exists in A3000Roms!)
3. A1200 / 020+
4. A4000 / 020+
5. CDTV / 68000 code & extended bootroms
6. CD32 / 020+ & extended bootroms

Benefits .. most important .. instantsupport for 4GB+ drives.
No more fingering on mystery partitontables and patches ...

Other Benefits ... its nice to have.
(Bigfixes)

Surely the best benefit is no reboot during the first boot after initial power-on.

If you have KS3.1 and are using OS3.9 it has to reboot to install the ROM patches.

...Always wondered if there was something wrong with my A1200... now i know...

Aye, its great to switch it on and have every patched / updated (with all the latest Boing Bag 1, 2, 3, 4 stuff).

Boots very quickly, without having to mess around with Startup-sequence entries.

Plus if your using a 1200, you can use 1MB ROM. So you can jam more into it, .

The updates always seemed some miner to me, almost pointless

except scsi.device

Everything in the updates worked for me without issue.
I only had problems, if I left libraries in the LIBS: dir.

Im talking from a ROM point of view.
As I moved them into ROM, they were no longer needed in LIBS: dir.

[Boo Boo]

Sorry I meant - the updates always seemed so minor - i.e theres no obvious improvements?

Sorry, my bad, I didnt read right, .

The latest unofficial boing bags help.

Sine installing the latest boing bag 4 to rom. I have gained 1 MIP in speed, need to test this further though, just aint had time yet.

[multivac]

Would a flash ROM and interface that plugs into the ROM sockets be possible?

Something for the hardware people to think about.

[alexh]

Already been done. It's just that an EPROM is much, much cheaper.

[Toni Wilen]

Proper flash adapter has not been done yet.

Plain 27C160 compatible DIP EPROM adapters that contain single SMD flash chip are not expensive (I have few and I think they cost less than 10euros).

Main problem is that they are not in-circuit programmable without Amiga specific extra logic chip (GAL or similar). Not much point in flash chip that can't be in-circuit programmed (of course flash can be erased and programmed very quickly compared to EPROMs but it only means ROM sockets will wear out even faster..)

No one has mass produced this kind of flash adapter (possibly including extra flash chip that works as a "boot rom" when main flash gets corrupted).

I am _still_ waiting for one

These do not work? AFAIK all that is needed is someone actually willing to build and sell them.

[Toni Wilen]

I have similar flash EPROM adapters but as you said, problem is modifying them to Amiga use.

If you have them factory made, "extras" like backup rom logic is easy to add (it is too easy to flash broken rom and then it is time for programmer and rom socket dies sooner or later.. and you have two roms on 32-bit Amigas. Argh. This is from developer's point of view, "normal" users probably won't do crazy tests too ragularly..)

btw, how does that circuit enable /ROMEN when writing, Gary does not do it and afaik it can't be done without active components and I don't see any in photos.

[rampartsagain]

does anyone have custom kickroms of 3.5 and 3.9 fully tested that can post for amiga 1200?

and does it eats more time during boot up???

[Jope]

No, they can't be posted here. Take ks rom piracy to private email please.

It doesn't eat any more time during bootup.

IMO the only 3.9 modules that are of real benefit to have right at poweron is the new early startup menu and the patched scsi.device. Perhaps also exec.library.

[SpeedGeek]

The OS ROM updates from 3.9 do not work reliably with all Amiga models. So if you get a reboot error you have to identify the offending module and then modify the startup-sequence with SkipRomUpdates. But this gets back to customizing 3.9 for your specific Amiga model.

You also save a few hundred KB of ram by using a custom 3.9 ROM. Using a 1 MB ROM can save you even more memory. Just don't ask for pirated ROM images to be posted in any Amiga forum.

[rampartsagain]

oh but if is piracy why persons make custom kickstart roms and no body produces them if they still have legal rights why don´t anybody produces under legal entity´s

thanks for the replys

[lifeschool]

^ Well as far as I understand it, the KS roms are the only aspect of Amiga Hardware Technology still actually owned by anybody related to the Amiga. They are the last element still copyright to Amiga Inc. For this reason (and the fact that the roms are really the only major illegal activity you can do with Amiga, as software piracy is just 'a given') so out of respect for the Amiga, and to save humble forums like this from being shut down by law enforcing busybodies, we have a gentlemans agreement not to share or copy roms. And as I say it's also a mark of respect for the machine. That doesn't mean illegal KS roms and cloned / hacked roms aren't available, and even licenced roms are available from Amiga Forever, but trading or sharing them is virtually the last taboo when it comes to respectable (ahem) forums such as this.

End of transmission. /

[rampartsagain]

hihihi
so we must do a delta force on a black op to kidnapp those guys and make them give up of their patent

anybody whant to list
WE WANT YOU!



well maybe i will hire the A TEAM!

[Jope]

It's all a double standard, but even so, we must adhere to this policy. We don't want the legal trouble from having software/firmware with actively enforced copyrights posted on here. Many people will burn KS roms for you, just ask around.

The only thing we moderators ask is that please don't post the KS images onto the boards. The copyright owners and licensees are still very active in protecting their intellectual property.

[rampartsagain]

shure jope i understand your point if i had i will burn them my self but i won´t bother more

jope can you fix my user account i am ramparts and my account is blocked i would like to get them back and close this one i tryed to send mails to administrator bur withno sucess it says waiting for user account validation but i can´t get to my personal email since site closed because of no use can you fix these???

many thanks

[LocalH]

For completeness, I'll also mention that WB disks are also included in the ban, as are IPFs that are not explicitly allowed to be freely distributed (I would assume that if a copyright holder allowed it, so would EAB, tho).

[rampartsagain]

i thought amiga inc had no more legal rights as have ended long last.

When is someone going to try OS4.x ROMS for classic.

[rampartsagain]

they didn´t reach there yet thimk only custom was 3.9 kickrom
not so many able to hold 4

I dont think that would work, as it would be disabling the 68k on boot and enabling PPC on boot. Not very practical if you want to run 68k OS (i.e. 3.9) on a dual boot.

[SpeedGeek]

** NEWS UPDATE **

I've been using 1MB 3.9 ROM's in my A3000/040 for 8 months now and it took me this long to realize Doobrey's "DummyCDstrap" hack does NOT provide cache enabled access to extended ROM!

So if you have a 1MB ROM(s) and a 68040 or 68060 and want cache enabled for extended ROM here are a few options for you!

1) Add this command from http://www.sinz.org/Michael.Sinz/Enforcer/Enforcer.lha to user startup: MMU address $E00000 size $80000 cache noshow

2) Install MMULib from http://aminet.net/util/libs/MMULib.lha and add this to MMU-config: Setcachemode 0xE00000 size 0x80000 ROM WRITETHROUGH

3) Downgrade your 68040 or 68060 to a 68030!

Enjoy!

[Foul]

Do not forget to include Kcon in your Custom ROM .. Great Benefit @ Boot !!!

Good point.

You can still load some system friendly games via the floppy drive after OS.4.x has loaded.

I just want someone to try to see if 1Mb roms work.
