Re: EtherH (I3 500 Podule) behaving strangely

Is it a duplex issue? Some NIC's default to half duplex, if not forced to full.

Re: RISC OS 3.20 ROM's?

On a '250 a full 4MB RISC OS ROM (not 2MB + 5th Column) fails the ROM checksum test (somehow), but I think you fixed that in a prior RO3.20 release? I have completely rewritten the way POST checks the ROM validity, instead of doing a full ROM check it now checks the Core and then each Module as its...

Re: RISC OS 3.20 ROM's?

Is VProtect actually useful these days? For 26bit OS it is advisable to run it, if you are using software from other sources. If you never download software, it can simply be unplugged to free up a bit of RMA. As I spent the time to create source for it for ADFFS, so I could fix the bugs, I plan to...

You should post the benchmarks.

Re: The Hidden Fifth Column: Integrating Wizzo with RISC OS 3.11

I'd use a larger ROM and embed an Extension ROM at the end, provided the Modules are ROM safe. If they're not ROM safe, I'd embed them into a Resource Module that RMLoads them - which is what I did in RISC OS 3.20. 5th column is 8 bit, so will always load the Modules into the RMA. Real world 5th col...

You need to double the speed of your A3010/20 to get about 75% speed of a Beeb. This is using 6502Em It's always fascinated me just how slow 6502 emulation on ARM has been to date. The BBC B ran at around 0.5 MIPS and I'm pretty sure a JIT could easily exceeded that on a stock ARM2. If I only had m...

IDE and the NIC share a READY signal. Connecting two drives to IDE will break the NIC, unless you fit a diode on the CF adapter. This is covered in this post.

I was under the impression that the RISC PC sorts out the monitor timings using an MDF file -- and thus doesn't need MonitorType to be set?
