APE on fast PC's

I have some trouble with the SIO communication (APE v2.0.6) on my 3000XP+ using 1 Chip design cable and RI Serial control.

Debug gives me:

Device:31, Command:53, Aux1:00, Aux2:00, Checksum:84

Followed by some

Device:31, Command:40, Aux1:4F, Aux2:4F, Checksum:2E

Than some

Device:4F, Command:40, Aux1:00, Aux2:00, Checksum:8F

Is there a general problem with APE on fast computers and/or anyone know how to solve this problem?

I use windows xp/sp1 (fresh installation) on an A7V8X

Had same problems with my Athlon XP2400+ system, with NVIDIA based motherboard though.

 

Steven Tucker suggested I try a PCI serial card based on 16550 UARTS -

Unfortunately it did not work for me, and I had to go back to using APE on another PC - but maybe it could be worth a go for you.

 

But...I wonder if it is an Athlon XP issue, because Stephen had said he tested with no problems on fast P4 systems.

This seems to have something to do with WinXP itself. (or perhaps APE's ability to access the UART thru the NT HAL??)

 

I have a PC on which I was successfully running APE under Win98SE.

 

I then wiped the HD and did a fresh install of XP Home on it. APE SIO totally stopped working. I could not get the SIO to work AT ALL.

 

I wiped the hard drive and reinstalled Win98SE. APE SIO PERFECT.

 

So, I guess my "APE Server" will remain Win98SE. Fine with me--it works juuust fine in Win98.

I have to disagree, APE works fine on my 566@733 celeron XP system.

What i did now is to disable the 2 level cache and underclocked the 3000xp+ to real 1,46Mhz.

APE seem to work fine than (most of the time, sometimes i have to reset the XL) BUT only if i run prime95 "torture test" to get heavy cpu load.

Underclocking or prime95 alone didn't work.
