Czy są przewidziane jakieś zmiany w projekcie? Np. dodanie akumulatorka podtrzymującego pamięć zegara albo możliwość ustawienia odczytu pliku config.sys z karty CF bez flashowania romu side?

* CONFIG's keyword MERGE now allows merging portions of CONFIG.SYS
  from arbitrary drive/path. Details:

The merged config file will be read using SDX device drivers, not OS
routines (as before). This allows drives/partitions that are accessible
only via SDX drivers (SIDE, MyIDE etc.) to hold the merged configuration
part for easy change. The main config should contain USE command (memory
configuration), device drivers (such as DEVICE SIO, DEVICE SIDE) and then
"MERGE filename.cfg" to attach the device-resident part of the
configuration.

Additionally, in case the filename contains either a device name, a drive
number or a path, the merged config will be loaded using SDX filesystem
drivers (such as SPARTA.SYS). This way a file from a different
directory/filesystem can be merged (for example MERGE
D2:>CONFIG>XTRA.CFG). Note that this requires SDX filesystem driver to be
loaded earlier (DEVICE SPARTA). Also beware that the merged files cannot
exceed 1KB.

If just the filename is given (like in previous SDX versions), the
filesystem drivers are not used to get the merged config. In such case the
merged file must be located in the same directory as the file that merges.
If the file is merged from the default config (CAR:CONFIG.SYS), it should
be stored in the root directory of the boot drive.

If no file name is given (MERGE without a parameter), SDX config selector
is invoked to let you choose from multitple CFG files stored in SPARTA.DOS
directory (see the manual for details). Note that in case of OS-compliant
boot drive, the config selector is shown regardless of MERGE command.
