Introduction
The Compaq/HP Presario 1115EA is a low/middle expensive, high performance laptop using a Celeron 1.6GHz and with 256Mb of RAM shared between system and ATi Mobility Radeon.
It is pretty and thin notebook with a brigth 14.1" TFT and weights around 3kg. It's a little brothers of Presario 2500 (see here the orginal doc by Thomas M. Breuel)
I started off by resizing the NTFS partition that it came with using Linux Mandrake 9.1rc2 partitioning tools (see here).
After resizing HTFS partition I rebooted the laptop into "the other OS" to check the filesystem coherency and then just did a regular Mandrake installation.
ACPI system
Configuring ACPI propely the battery could endure more tha 4 hours in text-only console.
Actually I'm working on swap suspend tool because it works quite well in hybernation of consolle.
But it corrupts the XFree VESA buffer [ 1 ] so much to make freeze the system when CTRL-ALT-F7 is pressed to switch back to the graphic session.
Linux Mandrake 9.1rc2 RPM packages about ACPI are:
acpid-1.0.1-1mdk
acpi-0.6-4mdk
suspend-scripts-1.3-1mdk
[ 1 ] I spoked about VESA Frame Buffer corruption because the garbage I saw on the display after the CTRL-ALT-F7 switch.
Built-In Sound Card
The built-in sound card is supported by the "trident" module. Working fine.
Built-In Ethernet
The built-in Ethernet is supported by the "natsemi" module. Working fine. I didn't test the boot from net possibility of this laptop yet.
Built-In Modem
The built-in modem is a Linux-supported soft-modem (see here).
By now there isn't a Linux Mandrake 9.1rc2 hsflinmodem driver delivered in RPM but it's possible to use the generic tar.gz package
Download the hsflinmodem driver delivered in tar.gz package and try to compile it. If you will see a error about a KERNELSRC unset variable you should execute this command from a root shell:
ln -s /usr/src/$(uname -r) /lib/modules/$(uname -r)/build
or if it doesn't work you should trying to modify common.mak a little bit about the path where it is looking for kernel sources
Graphics Card
The laptop has an ATI graphics accelerator but actualy there aren't any version of XFree that support its 3D. It's reasonable that it will be supported soon but in the meanwhile if you use "vesa" for the device, it works fine in 2D only.
This graphics card use the part of system memory, that portion is sizeable from BIOS: from 8Mb to 64Mb.
USB
I just tried it with a Compact Flash Card reader and it seems it worsk fine.
I experimented a drastic fall of performances (just loading vmlinuz) disabling USB Legacy from BIOS.
Synaptics TouchPad
I haven't tried to configure it yet, but you can get a utility for configuring the Synaptics TouchPad
here, others references here and here
You can use that to tune the sensitivity and tap-behavior. Even better, you can just plug in an external mouse and turn off the touch pad altogether (the button between the touch pad and the keyboard does the trick).
