18 | * Presently, a lot of graphics programs do not restore the contents of | |
19 | * the higher font pages. Defining this flag will avoid use of them, but | |
20 | * will lose support for PIO_FONTRESET. Note that many font operations are | |
21 | * not likely to work with these programs anyway; they need to be | |
22 | * fixed. The linux/Documentation directory includes a code snippet | |
23 | * to save and restore the text font. | |
