Hi to all,
first of all the config:
° A1200 mobo 1D4
° "Power M-disk (HD)
° DCE FlickerMagic
° Elbox PC-Key 1200
° HyperCOM 3+ clockport
° HK Computer Vector Maus & Joystick adapter (plus)
° modification to use hard reset
° Mediator PCI 1200
+ Terratec 512i (PCI)
+ Voodoo3000 16Mb (PCI)
+ D-Link DFE-530TX (PCI)
+ Elbox Spider II USB (PCI)
° Blizzard 603+ (50/240) + 256 Mb
° IDE-Fix 97
+ Maxtor 6Y080L0-YAR & PlexWriter PX-716A (on one cable)
+ LS120 (on the other cable)
Before yesterday I had no mod for reset and the CD was a generic 40x.
I had 3 partitions on the HD (1.0 Gb + 1.5 Gb + 2.0 Gb): OS3.9 in the first, data in the second, OS4.0 in the third... ALL FUNCTIONING!!!
Funny also that I used international FFS without long names for OS4... I didn't know anything about this...
Yesterday I made the mod and I changed the CD reader and I discovered what follows:
° OS4 did not boot anymore! I received the standard 3 colours blinking (red, blu, magenta) and then OS4 went rebooting continuously on the magenta screen (magenta + black + magenta + black...);
° I cannot use a better file system than FFS international!
+ For example if I have OS3.9 with international FFS on the first partition and a blank FFS + long names on the second one and nothing else... OS3.9 does not boot!!! ERROR!!!
° my only solution is to install OS4 with FFS international and WITHOUT using the Voodoo!!! Forcing AGA!!!

and this is also very strange since...
... OS4 installation is done with the Voodoo @ 800x600 and the AGA output after installation is through the Voodoo!!!
HEEEEEEEEEEELP!!!!!!!!!!!!!!!!!!
I have some ideas but I prefer to wait some help by you.
One note: I have not tried to remove the IDEFix since I do not have a cable 2.5 => 3.5 so I could not use an HD + CD.
Thanx to all!
