Hi,
I will repeat here what I wrote already as reply to another thread on this BBS.
1. Did you try to disable the primary IDE device and enable the secondary IDE device? In that case, what happens if you boot your device? I tried different boot order settings in the empty lines, and it looks like nothing changes at all with those settings.
2. As I already mentionned in another threat, some bios settings boot from a normal dos (win98) setup on a CF card and some boot from a CF card wich is made bootable with the HP boot utility and a USB -> CF card. If you cleared the Bios once (E. Kempen trick), you will need the HP utility prepared one. Once you can boot again from your CF slot, you can restore the NVRAM contents to it's default value, which makes the IA-1 boot from a normal Dos / Windows bootable CF disk.
3. It does seem that a microdrive only works reliable if the CF slot supply of the IA-1 is changed from 3.3 to 5V.
4. If you can't find the HP boot utility on the web, just give a yell on this BBS.
5. If you upgrade the CPU, you can run into Heat dissipation problems (the passive cooling block on the CPU doesn't cool enough which makes the IA-1 unstable after a long period of on-time.) and power supply problems (The supply of the IA-1 doesn't has much power reserve, especially if you start connecting USB devices).
To change the Bus speed of the CPU, you have to resolder a couple of very tiny SMD resistors which are used as links. I haven't tried it out yet.
6. Flashing the Bios chip with Uniflash.exe didn't work with my Blue IA-1's. I could reflash the internal 32Mb sandisk so that even if it boot's from there, it starts dos and gives access to some usefull tools. (those can make it boot from the CF-slot again.)
regards.
