adding device

[Chew Lek Wah]

Hi,

I need to add a software device (a RAM drive) and also a Standard 19200 bps
modem to my image. I've made a component out of the RAM drive drivers and
added it to my image. However it is not running in my image after FBA (FBA
didn't even detect it).
For the Standard 19200 bps modem, if i add it using the Phone and Modem
control applet, it will work but i would like FBA to do it for me
automatically.

I've been looking through the postings in the newsgroup for information in
adding device but still no luck. Anyone can help ?


Thanx in advance.

Regarding RAM driver.
You need to make component that will prepopulate some Enum, and Services
keys directly in the registry.
FBA can enumerate this driver since it is purely software driver, and there
is no bus driver for it to expose hardware id.

thanx for your reply.

do you mean to say that even the enums created by windows when i install the
driver need to be recreated by me otherwise it would not be detected ? i
notice that component designer did not import those settings into my
component. will try that.

any idea why the standard modem is not detected ?

I can't help you with modem, we don't need it since it is too slow for our
needs. Maybe in distant future I'll need to support ISDN, but this is
currently only considered as an possible option.
Try using google to search old archives.

Probably some Missing dependencies are giving the trouble.It could be
that the build is missing some primitive components or dll
dependencies(Dependency Walker should help you work on this).I would
add a inbuilt modem uncheck the auto dependencies and look out for the
entries.Compare this with the customised one if it exists.

thanx for your replies. i got the RAM drive to work when i added ALL
relevent registry (besides those detected when importing the inf file) as
mentioned by Slobodan.

For the modem, i would think tht the component created by microsoft
(standard 56000bps modem) would work without xtra tweaking.
i will try what Kesavan suggested.
