InstallAROS placing Quake's PAK files on the hard drive.
Work that, luckily, I had not to place in the dustbin. I only had to take some smarter decisions and change paths here and there. Today I finally managed to have something working, and it is encouraging: I can't boot yet straight from CD, however VmwAROS Live! is pretty functional and installs correctly on the hard drive. Most of the programs run fine from CD, too.
Next days' bugfixing session will correct wrong behavior of programs normally installed on DH0: (such as SimpleMail and Murks!), and when everything will be in a good shape, I will add the bootloader to the CD-ROM.
