Jordan is correct that having it undefined will work and give you an underscore cursor on a HGA display with the original code. My previous patch only works with FAT_CURSOR defined. I came up with a new patch that attempts to do the right thing in both cases. Jordan stated that the FAT_CURSOR can cause problems on certain HGA/MDA adaptors and with some of the <$15.00 made in Taiwan clones I can certainly believe this. All I can say is that with this new patch FAT_CURSOR works fine on my HGA adaptor and having it undefined still works as well. *** syscons.c.orig Sun Oct 17 01:49:48 1993 --- syscons.c Sun Oct 17 20:40:50 1993 *************** *** 310,320 **** printf(" <%d virtual consoles>\n", NCONS); else printf("\n"); - if (crtc_vga) { #ifdef FAT_CURSOR start = 0; end = 18; ! #else get_cursor_shape(&start, &end); #endif save_palette(); --- 310,321 ---- printf(" <%d virtual consoles>\n", NCONS); else printf("\n"); #ifdef FAT_CURSOR start = 0; end = 18; ! #endif ! if (crtc_vga) { ! #ifndef FAT_CURSOR get_cursor_shape(&start, &end); #endif save_palette();
