romfixes

[utri007]

Are you using this guide http://www.mfilos.com/2010/12/guide-create-and-burn-custom-kickstart.html

There is a small error, DummyCDStrap is needed if your CPU has a MMU, not just if you have BlizzardPPC. MMU blocks memory area used By extended part of rom, it will work but it is bog slow.

Did you managed to get this working, it is best possible scsi.device around http://aminet.net/package/driver/media/SCSI4345p

There is also a problem, needed exctractmodule command is not availlable where guide says, you can get it here http://aminet.net/package/util/boot/PatchRAM

Peterk's icon.library is also very usefull/excellent

Blizkick guide tells very well what those romfixes does?

Best thing with custom 1mb rom with newer scsi.device and filesystems is that it removes all the hasle with hard drives, prety much every hard drive works.

I don't know? Does it have it own scsi.device? My rom works just fine with ide-fix express, wich is similar product.

[utri007]

Most accelerators only support a 512kB kickstart for MAPROM. Hardware which supports a 1MB kickstart includes some ACA accelerators, Deneb, eFlash, and maybe some new FPGA accelerators and Amigas.

A4000 reguires additional tinkering to get it work with 1mb rom, but it is easy for A1200/A600. Even if accelerator doesn't support 1mb rom with maprom, it is still possible to get ROM to fast, easiest one is CPU FASTROM >NIL:

Blizkick doesn't support 1mb rom, but RemApollo 1.8 does http://www.ppa.pl/programy/remapollo-1.8.html

There is some disadvantages if workbench.library is left out, it can make life little harder certain problem situtations.

Forgive my ignorance on this topic. How tough would it be to make a ROM that would allow an Amiga boot from an attached CDrom drive (like all the other platforms can do). Only CDTV, A570, and CD32? can do this currently.

Nobody hasn't succeeded that. I tried to found cd filesystem wich would be rommable, I didin't found one. CDTV/CD32 filesystems doesn't work, I tested them.

[utri007]

Rommable cd filesystem could be handy, it would allow mounting cd-rom with any boot disk wich has normal 2.0-3.1 c: drawer. Could be time saving and make OS installation much easier, even if boot from cdrom wouldn't be possible.

When I made my custom rom, I wanted to make life easier. I would say I succeeded prety well. No more problems with hard drives, all poosible filesystems FFS/SFS/PFS, PCMCIA resest fixes and compaqflash.device wich does what  cd-rom couldn't, it mountable with any boot media.

There is no better scsi.device than 43.45 By Hodges, Wilen and Sauer. I tried 43.46 but soon found that version number of it, is just a number.

Info picture taken from EAB

There is a blizkick.guide inside of archive, all modules are descripted there.

[utri007]

Do you have a link to where the pic on EAB came from?

About CD Filesystems :

I have tried without luck

CacheCDFC
AmiCDFS
ASIMCDFS
BabelCDFS
CD32/CDTV cd filesystems

Only one wich I haven't tried is that Elbox cd filesystem.

[utri007]

I don't see much advantage to putting the CD file system in kickstart if it is not mounted early enough to boot off of. Most modern media has room to put the CD file system on the disk. Floppies would benefit as they have limited room but who is trying to use a CD with only floppies?

CD boot would be ultimate goal for custom kickstart.

But think about this:

Your hard drive is broken and you need to reinstall your sytem. You are trying to found your emergency boot disk, but is missing or doesn't work. Normally you would start to installing OS3.1 from floppy, preparing hard drive with it bit a problematic hdtoolbox. After that you need to put atapi.device and cd filesystem to floppy, install and configure it, so that you could actually install OS3.5/9 wich install it own cd filesystem and uses scsi.device.

With cd filesystem / latest scsis.device on ROM you coud boot from what ever floppy you can found like deluxe paint floppy, make a cd mountlist with text editor and mount it, after that you could start to preparing hd and installing OS.
