RedHat Linux
Initially established back in 1994, Red Hat (Wikipedia) is a commercial Linux vendor known for the RedHat Linux, Red Hat Enterprise Linux (RHEL) and Fedora Linux distributions.
RedHat Linux 7.3 (Valhalla) was released in 2002, and supported i386 through early Pentium 4 systems (the Intel Core based processors didn't ship until 2006). So it is suitable for comparing our physical Intel Pentium system (tilia) and the PCem emulated equivalent.
Earlier Releases
A couple of earlier Red Hat Linux releases are described on the same PCem system in:
It is interesting to see the evolution of the Red Hat Linux distribution over these releases.
PCem
The IBM PC and compatibles emulator PCem supports a range of PC system, from the original Intel 8088 based IBM PC through to a early 2000s slot 1 based Pentium II system. This includes a couple of systems featuring the Intel 430fx chipset which makes them equivalent to our physical system.
So the target emulated hardware is:
| Mainboard | Intel Advanced/ZP (Zappa); Intel Triton 82430FX PCIset aka. 430FX |
|---|---|
| CPU | Intel Pentium 75 |
| RAM | 72 MiB (128 MiB max.) |
| Floppy | 3.5" 2.88MB |
| Storage | IDE Controller Intel 82371FB aka. PIIX, ATA-2 16 MB/s |
| IDE hard disk 2048 GB | |
| ATAPI CD-ROM drive | |
| Video | S3 Trio64 based VGA |
| Network | 10Mb/s ethernet ISA |
