The software supplied with the bush stb is provided in two 32Mb Macronix mask ROMs. These cannot be re-programmed, their contents is fixed, they contain aproximately 5MB of software (the devices maximum is 8MB).
The supplied software is a version of RISC OS. This operating system has its origins in Acorn computers who created it as an operating system for their range of ARM based workstations. The original Acorn was broken up into various divisions one of which was Online Media who adapted RISC OS for use in set top box applications. The sub groups were recombined back into Acorn and re-named Element 14 Ltd. Element 14 Ltd was then split into E14 Ltd (still to this day owned by MSDW ), E14 Inc, and the rest (including RISC OS) was bought by Pace Micro Technology plc. Pace futher modified RISC OS for use in their own set top applications. This version (NC OS) is the one used in the Bush STB.
If you simply want to change the service provider you use that can be achived very simply. IOP Internet have a good reference for this. It comes down to typing in a simple password on the right screen and entering your ISP details. The process shouldnt be started unless you have all the required details for changing ISP. The steps are
| ISP name | The name that appears on screen when dialling |
| ISP telephone number | The Telephone number to dial |
| User name | The user name of your ISP account |
| Password | The password of your ISP account |
| Home URL | A URL the browser opens at start time |
| ISP domain name | The domain name of your ISP, usualy the same as appers to the right of the '@' symbol in your ISP provided email address |
| Primary DNS | Primary DNS server of your ISP, enter as a dotted quad |
| Secondary DNS | The backup DNS server of your ISP again a dotted quad |
| Dial Script | |
| E-mail URL | URL used when selecting the email feature |
| Search URL | URL used when selecting the search feature |
| Time server | Used to set the correct time |
| HTTP | This is the http proxy server of your ISP |
| FTP | This is the ftp proxy server of your ISP |

The password can apariently be obtained by running a BASIC command
DIM b% 255 : SYS "NVRAM_Read", "ISPCAccessPassword", b%, 255 TO
,b$ : PRINT b$.
For details on obtaining the command line and getting to BASIC see
later in the section.
One method of obtaining a command line in RISC OS is by holding
down the shift key while turning the unit on. This method appears to
work, however after boot the video section is disabled untill you
press the yellow "internet" key. Due to the "overscan" screen
resolution the box starts in you will probably not see the command
prompt (a single *), simply press the return key a few times untill
you can see the prompt. A mode 6 command will set the
screen to a non overscan mode.
The complete procedure is
mode 6 to get a better screen display
From a command line you can start the in built BASIC interpreter if
you wish, simply use the command BASIC. The BASIC
interpreter is fairly complete and is compatible with the one used in
workstation versions of RISC OS still sold by Risc OS Ltd..
If you have an old PPA zip drive they can be used with the STB the best resource for this is Getting a RISC OS desktop on the Bush IBX-100 by Chris Sawer this does require access to an RISC OS machine and some risc os knowledge however.
Several resources are available on the web to do with using RISC OS some places to start are Acornsearch and My RISC OS sites.
Any problems with this web page mail Vincent Sanders
There's lots more to the site! A good place to start is the Main Page.
