Hello cpiac64
do you have some pictures, what configurations are available on the card? From what I have read, the Cobra 1230 requires a firmware update to work with memory under Kickstart 3.1 I believe the source of this is on the available software - to upgrade the firmware you will need to remove the ram from the adapter and boot with the disks to install the firmware update (Thanks to amiga.resource.cx) The Cobra 1230 Manual (thanks to Installers Heaven) Utilities Disk and SCSI Install Disk hope that lot helps =) |

i have used the card with kickstart 3.1 and 3.0 without problem, i change the oscillator 40 mhz with 46.61512 because the 40 mhz is broken, i not used for one month whi i used a tqm for test and now i installed the cobra and the fast ram is zero with any module

Are you saying that there is NO fast ram at Cold boot (Power on), until you Three finger salute it ? (Warm Reset)
With my Cobra, I found the RF Shield was partly shorting out the card at its interface point to the motherboard in the trapdoor. I ended up totally bending the offending piece of RF shield out of the way so it didnt short it out. Symptoms I had, was in the range of Colored screens, No Fastram, to Just not booting. |
