65 | Initialize the browser to display the specified configuration forms.\r |
66 | \r | |
4ca9b6c4 LG |
67 | This function is the primary interface to the internal forms-based browser. \r |
68 | The forms browser will display forms associated with the specified Handles. \r | |
69 | The browser will select all forms in packages which have the specified Type \r | |
70 | and (for EFI_HII_PACKAGE_TYPE_GUID) the specified PackageGuid.\r | |
71 | \r | |
72 | @param This A pointer to the EFI_FORM_BROWSER2_PROTOCOL instance\r | |
73 | \r | |
74 | @param Handles A pointer to an array of Handles. This value should correspond \r | |
eecd469b | 75 | to the value of the HII form package that is required to be displayed.\r |
4ca9b6c4 LG |
76 | \r |
77 | @param HandleCount The number of Handles specified in Handle.\r | |
78 | \r | |
25a0aa5d | 79 | @param FormSetGuid This field points to the EFI_GUID which must match the Guid field or one of the\r |
80 | elements of the ClassId field in the EFI_IFR_FORM_SET op-code. If\r | |
81 | FormsetGuid is NULL, then this function will display the the form set class\r | |
82 | EFI_HII_PLATFORM_SETUP_FORMSET_GUID.\r | |
4ca9b6c4 | 83 | \r |
25a0aa5d | 84 | @param FormId This field specifies the identifier of the form within the form set to render as the first\r |
85 | displayable page. If this field has a value of 0x0000, then the Forms Browser will\r | |
86 | render the first enabled form in the form set.\r | |
