This package contains the source code for the Linux kernel in the TiVo Personal Television System software. The "linuxdist-2.1.24" source tree is configured for use on an Intel X86 development platform. The "linux-2.1" source tree is configured for use on the PowerPC-based hardware system on which the TiVo software actually runs.
Tiara is a BIOS replacement that boots an unmodified Linux kernel directly from the disk or the ethernet on any SiS 530/5595 Motherboard. It supports auto-sizing of memory and cache, PCI, IDE, VGA, SUPERIO, ENET, SOUND setup, and init. It supports the console on the std VGA(530) or via the SERIAL port(6801) from powerup, includes a Forth interpreter in flash and some diags, and fits nicely in 128kb of flash.
Thix is an almost complete implementation of the POSIX.1 standard (IEEE Std 1003.1-1988). It is a UNIX-like kernel with many features real operating systems have: virtual memory, demand paging, protection, swapping, etc. The Thix Operating System is fully functional at this time, and many free software packages have been succesfully compiled/run under it, including development tools such as the GNU C/C++ Compiler suite. However, there is no networking support and the only drivers available are for floppy disks, (E)IDE hard disks, printers, virtual terminals, mem, kmem and null.
SOLO (ShagOs LOader) is an x86 bootloader that can directly load and execute protected-mode 32-bit ELF, a.out, and plan9-a.out binaries. It contains a simple boot shell and can run customized scripts to provide boot menus, password protection, etc., at boot time. It comes with commands for scanning for available video modes, unzipping gzip'ed files, and a kernel interface that allows it to call back into 16-bit real mode for BIOS calls, etc. Some debugging facilities are also provided, such as default trap handlers and the ability to set a hardware breakpoint. The initial console I/O can be redirected over a serial port for headless systems.
