Re: AEH50 Ethernet II Podule

If you have the full universal boot installed, Open up !Boot (shift double click), and run !Boot.Resources.Configure.!InetSetup, there's a full GUI setup tool there that will save the config to the right place to be run on subsequent boot ups. Thanks flibble, I tried that too. It all seems to work ...

Re: AEH50 Ethernet II Podule

Ok, I have an older version of “universal” boot now and that recognises the card. IfConfig now lists the en0 interface but if I try to set the IP address ifconfig en0 inet 192.168.1.100 It throws an error: IfConfig: ioctl (SIOCAIFADDR): En module error #-o Showstat warns that Interface type 0 is not...

AEH50 Ethernet II Podule

Inspired by what Erik did with his Ethernet podule on an A5000 I've been trying to get network activity out of my Acorn AEH50 podule. So far without success. It is listed under *podules, but if I try to access it through ifconfig I get IfConfig: infconfig: socket: SWI &41200 not known Showstat runs,...

Re: Booting from ADFS harddrive into Wizzo IDEFS

Everything works OK as far as I can tell (not a single FileCore in use yet), bar a few hard-coded 'ADFS:' references, most notably in !Menon. The only real disadvantage is losing access to the floppy by default - I amended my boot sequence to check for the control key to skip the IDEFS loading/ADFS...

Failing ICs can give all kinds of behaviour, hard to predict. I’ve had a failing buffer chip that would read the drive, but with errors. From what you described imo the buffer chips are the most likely cause of the HD issues. If you do decide to replace them, see if you can cut the pins first so tha...

Well, it does not seem you are doing anything wrong. What hardware are you using exactly? Is this SuperMMC or TurboMMC? The card is a prime suspect, if you have an other MMC card it would be good to eliminate that as a cause. But it could also be caused by an other hardware issue. Check the user por...

I have an issue 3 that appeared quite dead - no video and no sound, only two of the leds would light up.

If you have the ARM3 upgrade, you will have the MEMC1a installed. The MEMC upgrade is needed for the ARM3 upgrade.

Re: Acorn Archimedes A310 with VIDC monitor recommendations

The trouble with connecting a VGA monitor directly to the analogue RGB port of an A310 without a VIDC enhancer is that you are stuck with the VGA modes. RiscOS applications are fine but most games will not run. So you either need a VIDC enhancer or 15KHz->VGA conversion hardware if you want to play ...

And back on topic: I thought it was necessary to replace the RISC OS roms to implement the Wizzo IDEFS on an A5000 but re-reading this thread, you only need to add a an eprom (and change the jumper on LK15 from S to N). Which I did on my A5000 and it works wonderfully! Very pleased with this! :D
