Hello all, i announce you the gfxboot COMBOOT module which is written in assembler. Since i didn't find as much spare time as i have hoped last weekend it is far from complete. Nevertheless the module is able to interact with the bincode ([1] and [2]) in the bootlogo cpio archive from the openSUSE 10.2 mini cd. So far it is able to call the bincode gfxboot code and setup some menu entries. Some callbacks (status, open and read) have already been implemented but it is missing a config file parser, so the menu entries are hard coded...

Calls to those functions only happen if the gfxboot core (bincode.asm) requests them. cb_status, cb_fopen and cb_fread are only called from gfxboot core (prim_findfile) if the requested file is not part of the bootlogo archive. cb_getcwd is deprecated, cb_chdir and cb_mount were never supported on upstream syslinux. The only function left is cb_readsector which...

This fixed the problem on OS X and aregImpute runs fine there. But with Hmisc 1.5-3, aregImpute now causes R to segfault on my linux box, viz: f <- aregImpute(~y + x1 + x2 + x3, n.impute=100) Iteration:1 Proce...

Going over my old notes, I realised that hist() has changed since the earlier versions of R, in that the intervals are now left-open,right-closed rather than the opposite. This is a change in the direction of S-plus compatibility, but I wonder how sensible it really is. The main problem is with ages, where you'd naturally take age 17 as representing something between 17 and 18, but: >

So here it is. Ugly and far from acceptable shape but nonetheless it seems to work. Parts are borrowed from syslinux core and of course the gfxboot patch for syslinux 3.63.
