2mb_rom

Open CCKMik opened this issue 4 years ago • 12 comments

I want to create a 2mb kickstart, to upload HD floppy disk (or more) with more amiga software, HOW to do it?

I cant see 2mb_rom patch, where is it?

Thx.

2MB is a bit of a mess. If you're using an A3000/A4000 you can use a 4MB ROMY and use the 4mb_rom patch (in romtool, not in romdisk, mind you)

On the A1200 it seems that a 2MB ROM is mapped to

0xA80000 - AFFFFF (512K) 0xB00000 - B7FFFF (512K) 0xE00000 - E7FFFF (512K) 0xF80000 - FFFFFF (512k)

So unless you find a good way of dealing with 2 (or rather 3) ext roms at non-consecutive addresses it seems tricky to place a large disk image there. That said, patches are welcome.

Remus can make 2mb roms

but it will not work,for me, witch romdisk.device :(

Sure. But again, the situation is not so trivial: Your image needs to look different depending on whether you are running on an A1200 or A3000/4000. And romdisk would need to understand how to spread your large file out over up to 3 noon consecutive 512k blocks. That code is not there right now, but you can probably add it if you are motivated to get this working.

I disagree. I use Remus for create a 2mb rom with romdisk.device and rodi file. And because I use Remus, I even use Kickstart 3.2.1 (adftools doesn't support beyond 3.1) I use 0xA80000 address for 1mb block, and don't use compression for adf/rodi file, so I have a 880ko full. Other extend memory 512k (e0) have libs and device on the rom And last main memory 512k (f8) is the original rom.

Hello, Unfortunately it doesn't work for me, what am I doing wrong? wrong order? wrong romdisk.device_rel ? I do not know.

I've tried almost all 2MB options and still no rom: in amiga early bootmenu

ps. 1MB works great.

Hello

Here my rpf for remus Rom A1200 2Mb I use Remus v1.81

just a trick, for F8 rom ADD Blizkick/2MB_ROM

Original file "2MB_ROM" doesn't work with 3.2.x or 3.1.4 (max 3.1) You need to use a patched file, I have the file, and no problem for give you, but I don't know how to share a file here.

Remus-rom1-E0-512k.rpf.txt

Remus-rom2-A8-1024k.rpf.txt

Remus-rom3-F8-512k.rpf.txt

for my RODI file, I use "-f nop", this authorize me to use a full 880Ko space disk. and I put RODI File in A8 Rom (1Mo)

I send you my rom and the 2mb file for build the f8 rom. I use romdisk.device_rel But I don't use the trackdisk.device, just keep the original file from your Kickstart.

thank you, it looks AWESOME.

but not very stable on my tf1260, freezes :(

CCKMik avatar Jan 04 '23 17:01 CCKMik

Hello. Strange, I don't have any issue. But I don't have TF anymore. Maybe because I add eide.device on the rom? Which condition for freeze? Try without the TF and same condition, if always freeze maybe is it your eprom faulty ? Last try, rebuild rom without ehide.device?

Ps : rom include Lha Lzx Hdtoolsbox with sfs and pfs3 already loaded Mount cf0: (compact flash) Mount cd0: (scsi.device 0) Mount cd1: (scsi.device 1) Setmap fr / us / uk for keyboard (défaut fr) A serial connection open, with serial cable and terminal, you can launch diagrom from another computer with a terminal (useful for troubleshoot if no screen) Diskmaster Xcopypro Redit Amigatestkit Tools for mount floppy adf and cdrom iso And off course a light workbench 3.2.1 And more tools...
