Subfunction: AL = 1Ah (get battery % charge)

Returns AL = % C, range 0 to 100%.

Subfunction: AL = 20h (get BIOS version)

Returns offset of BIOS version string in AX.

Segment is F000.

Subfunction: AL = 24h (BIOS Setup popup window)

Invokes the BIOS Setup window. Control is passed to the BIOS Setup

utility. The function returns when the user exits the Setup utility. The

video state is automatically saved and restored during this call. Returns

nothing.

This function requires the BIOS video save buffer to be available. If the

buffer is not available because another system popup window is in use

(such as the "battery change" window), this call is ignored.

Subfunction: AL = 26h (get/set vehicle mode)

Disallows battery charging when vehicle mode is ON and the battery

gauge percent charge register is greater than 90% (refer to subfunction

1A). This prevents excessive overcharging when the Allegro is

connected to an external power supply where the power is cycled on

and off frequently, such as in a vehicle. When vehicle mode is OFF,

charging is allowed no matter what value is in the percent charge
