OK. When trying to use Debian Bo and installing all the packages required(afaik) with dselect, I noticed that at a certain point, a write sector(s) command to the hard drive was failing for some weird reason, with busy status and DRDY set when it shouldn't.

Then I changed said behaviour to clear DRDY while BSY is active during the read/write data port part of transferring sector data(for both CD-ROMs and harddisks). Then I noticed it's still ends up with a 0x30 write sector(s) command in write data phase(thus DRQ=1) having 0x50 in it's status register and the message from some Linux write IRQ handler erroring out.
Then I looked at the write sector(s) code and noticed it was raising an IRQ with busy when starting the command after a big delay. Looked at the ATA-1 spec again, I noticed that an IRQ shouldn't be raised for that first sector transfer to start! Whoops!

Edit: Having fixed that issue, now the dselect install option seems to somehow loop installing packages over and over again?
At least it's not hanging anymore, which is a good thing, but it isn't proceeding onwards either(yet)?

OK. Python's configure script completed without visible issues. Then running make makes it complain about a missing inttypes.h at Include/pyport.h:6, included by Include/Python.h:63? Also -std=c99 isn't recognised by the compiler.

Anyone knows how to install the latest Python on Debian 1.3.1(codename Bo)?
