| After making the pcnet32 modifications I decided to test it again, on all three vms: VMWare, VBox and Qemu. I realised then that I haven't been testing the driver as thoroughly as I should have. The following table shows the results I get after downloading an 100mb image five times in a row.

| Someone should really make a test suite for drivers. Perhaps this would be a good first script. | Someone should really make a test suite for drivers. Perhaps this would be a good first script. | ||

| + | Tomorrow TODO: Finish patch, leave init_block like it was before, return error when MAC address is not valid. Post some details in the patch description, perhaps comparison against the old driver. | ||

| + | I finished the pcnet32 patch today and I uploaded version 2 of the patch. Hopefully, people will find it ok. Stefan reports some results in KVM and apparently disabling the BIOS console yields some definitive speed improvements which I will have to test too in VBox. | ||
| + | |||
| + | I also received a response from one of the forcedeth driver devs and it was awesome that he took some time to write me back. The forcedeth driver writing will mostly be a direct port of the Linux one. | ||
| + | |||
| + | Another small project rose up today, I have to find out why gPXE is so slow in VBox. I don't know yet if the BIOS thing is causing it, but I will find out these days. | ||

| + | |||
| + | Version 3 of the patch is up. At this rate, I will probably hold the record for most revisions of a patch :). Also sent an email to Andrew de Quincey regarding forcedeth documentation. | ||
