Re: Making a wifi bridge so risc os can work any where in ho

For me it was cheaper to buy a second hand notebook £20 then use another pi + wifi dongle and power supply that comes nearer the £30 mark and a full mains wifi bridge is £35 and above, but I bett most pi users have at least one laptop/netbook in the house that they can use as a bridge and it will co...

Re: making a 30gb SDcard using a 32gb SDcard for Risc os

As to the fat 16 placement I put it in the same place as I found it on the original RISC os sd card, the start position on the RISC os sdcard was 10 Bytes and does it reflect in both file and partition I will check later.

Re: making a 30gb SDcard using a 32gb SDcard for Risc os

Another point. When you format a 2gb disc the sector byte size is 512 bytes by default and 4096 bytes when you format a 30gb because of this the files should never get over written. the files on the larger filecore on have more room to play with. or am I totally missing the point?

question. if the dos partition didn't align then surely i couldn't access the files in the dos partition from risc os. ie from !boot.Loader dir as i can access the config/txt file and alter it surely the partition must align and the original pointer file valid? or i'd just get back garbage from the ...
